PURPOSE:To make an exposed fitting surface of a header by a method wherein a circumference edge of a backside of a substrate corresponding to the part of the substrate covered with resin is recessed by one step and the resin flowing round to the backside of the header is stored in a space of the recessed part. CONSTITUTION:A recessed part 7 is provided on a circumference edge of a backside surface corresponding to a part of a main surface of a header 1 molded with resin. After molding, the recessed part 7 and a package 3 form a groove 8. The groove 8 is utilized as a resin storage where the resin creeping to the backside of the header 1 during resin molding is stored. With this constitution, even if resin flush is produced, it is stored in the recess 7 and does not flow over the recess 7 to spread on the wide flat surface of the header 1 which is to be the fitting surface. |
