Inductor built-in substrate and method for manufacturing the same

An inductor built-in substrate includes a core substrate having openings, a magnetic resin filled in the openings and having through holes, and through-hole conductors formed in the through holes respectively such that each of the through-hole conductors includes a metal film. The magnetic resin is...

description An inductor built-in substrate includes a core substrate having openings, a magnetic resin filled in the openings and having through holes, and through-hole conductors formed in the through holes respectively such that each of the through-hole conductors includes a metal film. The magnetic resin is formed such that each of the through holes has an angle part having an obtuse angle formed by an upper surface of the magnetic resin and a side wall of a respective one of the through holes.
