To provide a structure for preventing the pattern peeling of a leg portion in a connection electric component capable of withstanding actual terminal insertion/ejection, terminal dead load, and terminal gouging force by soldering from the signal terminal pattern of the connection electric component, such as a jack, to the land of the leg of another component, and capable of corresponding to the revision of a standard in an external terminal strength test.

The structure is packaged onto a printed circuit board 1, and prevents the pattern peeling of a leg 3 in the connection electric component, such as the jack 2 connected by insertion and ejection from the outside. A solder portion H in the leg 3 of the connection electric component is connected from the signal terminal pattern of the connection electric component to the leg land of another component, such as an axial coil 5 packaged onto the printed circuit board 1.
