    • A method for manufacturing a printed wiring board includes preparing a core substrate having first and second surfaces, forming a penetrating hole from the first surface toward the second surface of the substrate, forming first conductor on the first surface of the substrate, forming second conductor on the second surface of the substrate, and filling conductive material in the hole such that through-hole conductor connecting the first and second conductors is formed. The forming of the hole includes forming a first opening portion on the first-surface side of the substrate, a second opening portion from the bottom of the first portion toward the second surface, and a third opening portion from the bottom of the second portion toward the second surface, and the forming of the hole satisfies X2

    • A method for manufacturing a printed wiring board including forming a penetrating hole in a core substrate, forming a first conductor on a first surface of the substrate, forming a second conductor on a second surface of the substrate, and filling a conductive material in the hole such that a through-hole conductor is formed in the hole and the first and second conductors are connected via the through-hole conductor. The forming of the hole includes forming a first opening in the first surface, forming a second opening from the bottom of the first opening toward the second surface such that the second opening has a smaller diameter than the first opening, forming a third opening in the second surface, and forming a fourth opening from the bottom of the third opening toward the first surface such that the fourth opening has a smaller diameter than the third opening.
