PURPOSE:To prevent the deterioration of electric characteristics owing to electric discontinuity in an RF signal path between an electric part and a board, and shorten an electric adjusting time and an assembling time. CONSTITUTION:Slitting is performed on a metal cylinder bar so that the lead pin 1 of an electric part 5 can be inserted thereto, and a contact pin 3 is formed. By inserting the lead pin 1 of the electric part 5 to the contact pin 3, and soldering the opposite side of a slotted portion to a connection board 2, the electric part 5 and the connection board 2 are connected mutually. The lead pin 1 and the contact pin 3 are put into contact by spring force, so that the lead pin 1 and the contact pin 3 slide each other at a touching portion. Thereby, a distance change portion between the electric part 5 and the connection board 2 caused by the difference of metal elongation percentages owing to the difference of the coefficients of thermal expansion is absorbed so as to prevent the occurrence of stress. |
