PROBLEM TO BE SOLVED: To restrain a projecting quantity of a burring projection from a substrate to a minimum without causing any deterioration of a resin base by forming the burring projection on a terminal board, threading a female screw on the inner circumference of the burring projection, and inserting the burring projection into a through hole. SOLUTION: A terminal board 6 comprises a burring projection 7, a cutout 8, a soldered portion 9 and a tightening portion 11. The burring projection 7 has a hole having a burr by burring. A female screw 12 is formed on the inner circumference of the burring projection 7. A guide pin 18 of a base 1 is inserted into a guide hole 5 formed on a base board 3. A connecting hole 4 is put opposite to a through hole 2. The burring projection 7 is inserted into the connecting hole 4 and the through hole 2. At this time, the guide pin 18 is fitted into the cutout 8 of the terminal board, thus positioning the terminal board 6. |
