Abstract

PROBLEM TO BE SOLVED: To prevent a lateral shift of a lead plate surely by bonding one end part of the lead plate to one modular board through a heat resistant adhesive. SOLUTION: One end part 7a of a lead plate 7 is mounted on the upper surface of each connection pad 5 of one modular board 1 out of two modular boards 1, 2 arranged in parallel and soldered 8 to the connection pad 5. A heat resistant adhesive 9 is then applied partially to one end part 7a of the lead plate 7 while being spread to the one end part 7a and the modular board 1 and dried thus bonding the one end part 7a of the lead plate 7 to the modular board 1. Subsequently, the other end part 7b of the lead plate 7 is mounted on the upper surface of a connection pad 6 of the other modular board 2 and soldered 8 to the connection pad 6.
