Abstract
A substrate intermediary body includes: a substrate having a hole in a thickness direction, and a conductor being disposed in the hole; and an adhesion layer formed on a wall surface of the hole. The adhesion layer contains a reaction product of a polymer (A) having a cationic functional group and having a weight-average molecular weight of from 2,000 to 1,000,000 and a polyvalent carboxylic acid compound (B) having two or more carboxyl groups per molecule or a derivative thereof.
