Abstract: An electronic device 10 comprises chip capacitors 20a and 20b, an accommodation recess 62 accommodating the chip capacitors 20a and 20b, and a case 60 including a protrusion 64 partitioning the accommodation recess 62 into a first accommodation space 62a and a second accommodation space 62b along the X-axis direction. The protrusion 64 includes a first protrusion 64a and a second protrusion 64b disposed away from the first protrusion 64a along the Y-axis direction. The first protrusion 64a and the second protrusion 64b are disposed with a communication space 69 provided between the first protrusion 64a and the second protrusion 64b, so that the first accommodation space 62a and the second accommodation space 62b communicate.

Abstract: An electronic device includes a chip component and a metal terminal. The chip component has an element body where internal electrodes are laminated inside and a terminal electrode formed outside the element body and connected with end parts of the internal electrodes. The metal terminal is connected with the terminal electrode of the chip component. The metal terminal includes an electrode face portion and a mount portion. The electrode face portion is arranged correspondingly with an end surface of the terminal electrode. The mount portion is mounted on a mount surface. The electrode face portion is provided with an opening portion so that a part of the terminal electrode corresponding with at least a part of the internal electrodes is exposed to the outside.

Abstract: An electronic device includes a chip component and a metal terminal. The chip component includes a terminal electrode formed on an element body. The metal terminal is connectable with the terminal electrode of the chip component. The metal terminal includes a terminal body and a pair of holding pieces. The terminal body faces an end surface of the terminal electrode of the chip component. The pair of holding pieces is formed on the terminal body and sandwiches the chip component. A width, a protrusion length, or a protrusion area of one of the pair of holding pieces is different from that of the other holding piece.

The terminal body faces an end surface of the terminal electrode of the chip component. The holding pieces are formed on the terminal body. A connection member configured to connect the terminal body and the end surface of the terminal body exists in a joint region between the terminal body and the end surface of the terminal electrode. A pair of reinforcement pieces is formed on the terminal body so as not to overlap with the joint region in a direction extending from one to the other of the pair of holding pieces.

Abstract: An electronic device includes first and second capacitors, a case, a coil, and first to fourth conductive terminals. The first capacitor includes first and second terminal electrodes. The second capacitor includes third and fourth terminal electrodes. The case includes an accommodation recess for accommodating the first and second capacitors. The coil is separated from the first and second capacitors by a part of the case and disposed outside the accommodation recess. The first terminal is connected to the first electrode and partly disposed on a mounting-side bottom surface of the case. The second terminal is connected to one end of the coil and the second electrode and partly disposed on the surface. The third terminal is connected to the other end of the coil and the third electrode and partly disposed on the surface. The fourth terminal is connected to the fourth electrode and partly disposed on the surface.

Abstract: A conductive terminal includes an inner electrode part, an opening edge electrode part, and a lateral electrode part. The inner electrode part is connectable to a terminal electrode of a chip component by being inserted along an inner wall of an accommodation recess of a case. The opening edge electrode part is formed continuously to the inner electrode part. The lateral electrode part is formed continuously to the opening edge electrode part along an outer surface of the case. The inner electrode part includes a base part, a curved part, and a continuous boundary part. The base part continues to the opening edge electrode part. The curved part is formed near a tip of the base part and protrudes away from the lateral electrode part. The continuous boundary part is formed between the base part and the curved part and continuously connects them.

Abstract: An electronic device includes chip components, a terminal connection body, conductive terminals, and a support member. Each of the chip components has a pair of end surfaces on which terminal electrodes are formed. The terminal connection body connects the terminal electrodes on one side of the chip components arranged next to each other in a parallel direction to the end surfaces. Each of the conductive terminals includes a connection part and a mount part. The connection part is connected with the terminal electrode of either of the chip components located on both ends of the chip components connected in series via the terminal connection body. The mount part faces the connection part and is connected with a mount board. The support member is disposed between the connection parts and the mount parts. The chip components are arranged so that the end surfaces face the mount board.
