PROBLEM TO BE SOLVED: To easily and reliably increase a printed circuit board. SOLUTION: A screw fastening body 21 which is soldered to a master board A and has a screw-fitting hole part 22 to which an increased board B is fixed by a screw 41 and plural contactors 31 to electrically connect the master board A and the increased board B to each other, are integrally arranged in a device body 11 molded by an insulating material. The device body 11 has grooves 13 and 15 in which the screw fastening body 21 and the contactors 31 are respectively pressed, and the screw fastening body 21 and the contactors 31 are respectively pressed and installed in these grooves 13 and 15. The master board A and the increased board B are mechanically connected to each other by the screw fastening body 21, and connecting strength is secured, and they are electrically connected to each other by the contactors 31. The screw fastening body 21 electrically connects both boards A and B to each other by a screw-fitting part forming surface part 23 of conductive metal in which the screw 41 is screw- fitted and a projecting part 27. |
