Abstract
A prepreg having an opening portion is placed on a cover lay which covers conductive circuits formed on a basefilm. A copper foil sheet is placed on the prepreg in such a way that the copper foil sheet covers the opening portion. The copper foil sheet has no opening portion. Next, the basefilm, the prepreg, and the copper foil are thermocompressed to become one laminate. After making a hole in the laminate, the laminate is plated, and then a through-hole is formed. A conductive circuit is formed by etching the copper foil sheet.
