An interposer producing method comprises the steps of forming a seed layer (14) in the opening in a through-hole (13) on the back (12) side of a base plate (10), forming a plating electrode layer (15) on the basis of the seed layer (14), and forming a plated layer (16) on the face (11) side of the base plate (10) to fill the through-hole (13). As a result, it is possible to provide an interposer producing method in which the production process is easy and no blowhole is produced in the through-hole. |
