Zusammenfassung:An interconnect substrate includes an insulating layer, an electrode disposed on the insulating layer and having a first surface not covered with the insulating layer, and an external connection terminal disposed on the first surface of the electrode, wherein the electrode has a recess in the first surface, wherein the external connection terminal includes a first conductor filling the recess and a second conductor disposed on the first conductor, and a melting point of the first conductor is higher than a melting point of the second conductor, and wherein a metal material of the electrode is different from a metal material of the first conductor.
