Abstract: In a substrate, at least one lateral surface between one surface and another surface is a cut surface that is cut together with mold resin. The mold resin, which is cut together with the substrate, is provided with a surface that is flush with the cut surface. A portion of the mold resin constituting the surface flush with the cut surface has a surface that is joined to the surface flush with the cut surface and parallel to the one surface of the substrate; this portion is thinner than a portion that seals electronic parts. Consequently, the mold resin is cut with a dicing blade brought into contact with a surface parallel to the one surface of the substrate.

Abstract: A mold package includes a substrate having a first surface and a second surface disposed opposite to the first surface, a wiring part disposed on the first surface in protruded manner, a molding resin, and a resin film. The molding resin partially seals the first surface of the substrate and the wiring part and intersects with the wiring part. The resin film is disposed between the first surface of the substrate and the end of the molding resin, and seals the wiring part and the first surface of the substrate adjacent to the wiring part. The resin film includes a first portion disposed inside the molding resin and a second portion disposed outside the molding resin. An upper surface of the second portion is lower than an upper surface of the first portion and has less uneven portions than the upper surface of the first portion.
