Abstract:
1. An electronic device comprising: a printed circuit board that has a first surface and a second surface and that includes a plurality of lands; and an electronic element that has a body and a plurality of terminals extending from the body, wherein: the electronic element is disposed on the first surface of the printed circuit board in such a manner that the plurality of terminals is arranged on the first surface in a predetermined direction; the plurality of terminals is coupled with the plurality of lands respectively; the printed circuit board further has a through hole extending from the first surface to the second surface; one of the plurality of lands includes a surface land disposed on the first surface of the printed circuit board and an insertion land integrally disposed on a sidewall of the through hole and on a periphery around the through hole; one of the plurality of terminals includes a surface section and an insertion section; the surface section is disposed on the surface land in such a manner that an attaching surface of the surface section faces the surface land, and the surface section is coupled with the surface land through a solder; the insertion section is disposed in the through hole and is coupled with the insertion land through the solder; the surface section has a recess part on the attaching-surface side; and a portion of recess part is disposed so as to be axially aligned with a portion of the through hole.
