PURPOSE:To reduce the number of parts items and assembly man-hours, and keep easily an insulation distance between pins by providing a pattern part in which the protrusion axis of a resin base is connected with the terminal pins chemically plated, and by connecting as circuitry pattern, provided on the lower surface of the base, with the terminal pins via through-holes. CONSTITUTION:Mounting flange parts are provided at the peripheries of a base 1, and a cylindrical key part 11 and eleven protrusion axes 12 are projected. Through-holes 13 are provided corresponding to the protrusion axes 12. The protrusion axes 12 are chemically plated to form terminal pins 2. The peripheral part containing pins 2 and through-holes 13 are chemically plated to form a pattern part 3, and are connected with pins 2. A circuitry pattern 4 corresponding to the pattern part 3 are formed by chemical plating on the back surface of the base 1. The pattern 4 is connected with the terminal pins 2 via through-holes 5. |
