PURPOSE:To test and measure even a printed circuit board having contacts at a pitch smaller than a reference pitch, by inserting an adapter pin in the through-hole of a top board from below and connecting a flexible conductor to the lower part of said pin. CONSTITUTION:Adaptor pins 16 are inserted in the through-holes 13a of a top board 13 from below to be engaged therewith. One ends of flexible conductors 18 are connected to the lower parts of the adaptor pins 16 and a connector 17 is connected to the other ends of the flexible conductors 18. The connector 17 is engaged with the pins 11b of a bottom board 11. In this state, a printed circuit board 30 is arranged on the adaptor pins 16 and the adaptor pins 16 are brought into contact with the contacts 31 while the contacts 31 are electrically connected to probe pins 21.
