Abstract: A ceramic electronic device includes a ceramic element body, a terminal electrode, and a lead terminal. The ceramic element body has an end surface and a lateral surface. The terminal electrode is formed on from the end surface to a part of the lateral surface of the ceramic element body. The lead terminal is connected to the terminal electrode by a connection member. The lead terminal includes an electrode facing portion disposed correspondingly to an end-surface electrode of the terminal electrode, an extension unit extending downward from a lower end of the electrode facing portion, and a step surface located between the electrode facing portion and the extension unit. The electrode facing portion has a recess dented in a direction away from the terminal electrode. A center of the recess is located below a center of the electrode facing portion in a height direction.

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 a plurality of chip components and an insulating case. The chip components are arranged in a first direction. The case includes a plate portion, a first protrusion portion, and a second protrusion portion. The plate portion faces first side surfaces of the chip components. The first protrusion portion is formed along a plate-portion first side of the plate portion and protrudes from the plate portion toward a downside perpendicular to the first direction. The second protrusion portion is formed to the first protrusion portion in a second direction and protrudes from the plate portion toward the downside. A protrusion length of the first protrusion portion and the second protrusion portion from the plate portion toward the downside is smaller than a protrusion length of the chip component included in the chip components from the plate portion toward the downside.
