Therefore, since the seed layer 8 is formed on the entire peripheral surface of the upper end portion 7a and the step 7b of the mold through via 7, the contact area between the mold through via 7 and the protective film 1 can be increased. As a result, the adhesion between the protective film 1 and the mold through via 7 is improved, and it is possible to prevent collapse and misalignment. In addition, peeling is less likely to occur even when stress due to temperature change, mechanical external force, or the like is applied.
