摘要： In a coil 5 of a multilayer coil component 1, an end portion 6a of a turn 6 closest to a side surface 2e in the facing direction of the side surface 2e and a side surface 2f is connected to a first external electrode 3 and an end portion 11a of a turn 11 closest to the side surface 2f in the facing direction of the pair of side surfaces 2e and 2f is connected to a second external electrode 4. The area at which the turn 6 faces the second external electrode 4 and the area at which the turn 11 faces the first external electrode 3 are smaller than the area at which turns 7, 8, 9, and 10 other than the turn 6 and the turn 11 face the first external electrode 3 or the second external electrode 4.

摘要： A multilayer coil component includes an element body, a coil disposed in the element body, and a terminal electrode disposed on the element body. The element body has a first side face and a second side face, a first end face and a second end face, and a first main face and a second main face. The terminal electrode includes a first electrode portion and a second electrode portion. The first electrode portion has a first exposed face exposed on the first main face. The second electrode portion has a second exposed face exposed on the first end face. The first exposed face and the second exposed face are adjacent to each other interposing a ridge portion. The first exposed face is separated from an outer edge of the first main face. The second exposed face is separated from an outer edge of the first end face.

摘要： In a coil 5 of a multilayer coil component 1, an end portion 6a of a turn 6 closest to a side surface 2e in the facing direction of the side surface 2e and a side surface 2f is connected to a first external electrode 3 and an end portion 11a of a turn 11 closest to the side surface 2f in the facing direction is connected to a second external electrode 4. When viewed from the facing direction, the area of the region where the turn 6 and the second external electrode 4 face each other and the area of the region where the turn 11 and the first external electrode 3 face each other are larger than the area of the region where turns other than the turn 6 and the turn 11 and the first external electrode 3 or the second external electrode 4 face each other.

摘要： The electronic component includes an element body, a first external electrode, and a second external electrode. The first external electrode and the second external electrode are disposed on a principal surface and are separated from each other in a first direction. The first external electrode includes a first region and a second region. The first region includes an end edge that opposes the second external electrode in the first direction and is located inside the element body. The second region is continuous with the first region and is exposed from the principal surface. The second external electrode includes a third region and a fourth region. The third region includes an edge that opposes the first region in the first direction and is located inside the element body. The fourth region is continuous with the third region and is exposed from the principal surface.

摘要： A multilayer coil component 1 includes an element body 2, a pair of terminal electrodes 3, and a glass layer G provided on the terminal electrode 3. Each of the pair of terminal electrodes 3 is provided with a plurality of first projecting portions 33 tapered toward the other facing terminal electrode 3 side in an end portion 31b facing the side in the facing direction of a pair of end surfaces 2a and 2b. The glass layer G is provided along the edge of the terminal electrode 3 including at least the first projecting portion 33 in the end portion 31b of the terminal electrode 3.
