Abstract
An electronic device includes a printed circuit board and an electronic element having a terminal. The terminal has a surface section and an insertion section. The printed circuit board includes a through hole extending from a first surface to a second surface of the printed circuit board, a surface land disposed on the first surface, and an insertion land integrally disposed on a sidewall of the through hole and on a periphery around the through hole. 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 and a portion of recess part is disposed so as to be axially aligned with a portion of the through hole.
