PROBLEM TO BE SOLVED: To enable a part of a socket that protrudes towards the underside of a board to be lessened in size, by a method wherein a part of a resin molded part that protrudes towards the underside of an island is made to serve as a socket where the electric connecting plane of the outer leads of leas pins is exposed, and the lower part of the socket can be cut off. SOLUTION: In a socket 12, electrical mounting connecting surfaces are formed on the side faces of the outer leads of lead pins 4 arranged in parallel confronting each other, and electric connecting surfaces for a continuity test are provided to the lower edge faces of the outer leads, and a hollow 20 that is not filled up with resin is provided between the outer leads which confront each other in a lateral direction. Furthermore, a cutting groove 21 is provided to the cutting part of the lower part 12a of the socket part 12, a beam 22 is provided inside the hollow 20 in one piece by resin molding along a cutting line, and the lower part 12a of the socket 12 can be cut off along the cut groove 21. After mounting, the lower part of a socket is cut off, whereby a part of the socket protruding toward the underside of a board can be lessened in size. |
