PROBLEM TO BE SOLVED: To mount an electric part with lead wires and a surface-mount part in the same hole. SOLUTION: This printed wiring board has a structure where the base-side inside of a blind conduction hole 3 is made hollow, a copper-plated laminate 2 is provided with a through-hole at a prescribed position, a copper foil 2A is provided to the underside of the copper-plated laminate 2 in one piece so to become the outer surface of the underside of the laminate 2 for the formation of the blind conduction hole 3, an electric part with lead wires can be mounted on the wiring board inserting its lead wires into the conduction hole 3, and a surface-mounting part can be densely mounted on a surface-mount part land provided to the upside of the blind conduction hole 3. |
