Abstract

PURPOSE:To enable the sure soldering of external connection leads, and improve the workability of soldering process, by arranging a protruding part of the external connection lead in the cross direction of the arrangement direction of external connection lead inserting lands, and soldering the protruding part to the external connection lead inserting land. CONSTITUTION:An external connection lead 22 is inserted into a land hole 30, and connected electrically to an electronic parts 21. A plurality of external connection lead inserting lands 29 are disposed in an array on a mother circuit board 23. The external connection lead 22 is provided with a protruding part 22a for positioning to regulate the insertion degree with respect to the land hole 30. In this printed circuit board, the protruding part 22a of the above external connection lead 22 is made to protrude with a space in the cross direction from the arrangement direction of external connection lead inserting lands 29, and soldered to the land 29. For example, the above protruding part 22a is bent in the vertical direction to the arrangement direction of external connection lead inserting lands 29, and the lower surface of its bent tip part is brought into contact with the upper surface of the mother printed circuit board 23.
