PURPOSE:To prevent an error of an inspection even in the case of a substrate in which a position of parts is not determined by providing a cushion material having elasticity on a printed board side of a base material having rigidity, and pressing the printed board through the cushion material. CONSTITUTION:A jig 1 attached to the tip of a press equipment 9 is constituted of a base material 2 having rigidity and a cushion material 3, and presses a printed board 4 through the cushion material 3. The printed board is constrained as to its movement in the horizontal direction by a guide member 8, supported by a conductive inspection use pin 5, and on its upper face, electronic parts are placed. Even if that which is not determined as to its position, for instance, such as harness 7, etc. exists in the electronic parts, since the jig 1 has the cushion material, it does not occur that excessive force works locally, the whole printed board 4 can be pressed uniformly, and an error of an inspection can be prevented.
