PURPOSE: To provide a relatively economical wiring board wherein a part can be connected to a through-hole without soldering, a part can be exchanged readily and a part mounting height is not so large.
CONSTITUTION: Insulation substrates 7, 8 with lead terminal insertion holes 7a, 8a in a position opposite to a through-hole 2 are laminated up and down a wiring substrate 1 with the through-hole 2. A lamination body 21 formed as above is held between frame bodies 9 and the wiring substrate 1 and the insulation substrates 7, 8 are held to freely slide each other. By the sliding, while a lead terminal 3a inserted to the through-hole 2 of the lamination body 21 and a lead terminal insertion hole 7a up and down thereof are in pressure contact with an inner circumferential surface of the through-hole 2, the wiring substrate 1 and the insulation substrates 7, 8 are locked by a screw-type lock means 10. A screw hole of a frame body which fits to a screw 10a of the lock means 10 is a round hole. Among an insulation substrate and a wiring substrate, one which is slid has a long hole and the other has a round hole.
