Abstract
A module is provided that includes a substrate having a first main surface, a component mounted on the first main surface, a first sealing resin disposed so as to cover the first main surface and the component, and a shield film covering at least an upper surface of the first sealing resin. The shield film includes a protective layer exposed to the outside and a conductive layer covered by the protective layer. The color of a surface of the conductive layer closer to the protective layer is different from the color of the protective layer. Moreover, the laser absorption coefficient of a material of the protective layer is higher than the laser absorption coefficient of a material forming the surface of the conductive layer closer to the protective layer. The module includes a marking section that is not covered by the protective layer and from which the conductive layer is exposed.
