Disclosed is a semiconductor device wherein the adhesion of resin to a substrate is improved at a low cost. A semiconductor element and one or two substrates opposing one or both of the surfaces of the semiconductor element are sealed by a resin, a resin bonding coat which is formed by spraying a metal powder by a cold spray method is formed on one or both of the substrates, and recess portions which are widened from a film surface in a depth direction are formed on the resin bonding coat.
