Module
A module includes: a substrate having a first face; a plurality of components mounted on the first face; a resin film that covers the plurality of components along contours of the plurality of components and also covers a part of the first face; and a shield film formed to overlap the resin film. The first face is provided with a ground electrode. The resin film has an opening, and the shield film is connected to the ground electrode via the opening.
1. A module comprising:
a substrate having a first face;
a plurality of components mounted on the first face;
a resin film covering the plurality of components along contours of the plurality of components and also covering a part of the first face; and
a shield film provided to overlap the resin film,

the shield film has a dot-shaped recess corresponding to the opening,
the shield film is separated by a slit, and wherein the first face of the substrate is exposed to an outside of said module via said slit, and
the slit is provided in a region where a two-layer structure comprising the resin film and the shield film covers the first face of the substrate directly.
2. The module according to claim 1 , wherein a distance between the shield film and a surface of each of the plurality of components is constant.
3. The module according to claim 1 , wherein the module has a conductive material disposed in the opening of the resin film so as to cover a portion where the ground electrode and the shield film overlap.
4. The module according to claim 1 , wherein the module has a conductive material interposed between the ground electrode and the shield film in the opening of the resin film.
5. The module according to claim 1 , wherein the opening is located between the plurality of components.
6. The module according to claim 1 , further comprising an antenna.
7. The module according to claim 6 , wherein the substrate has a second face as a face opposite to the first face, and the antenna is disposed inside the substrate along the second face.
8. The module according to claim 2 , wherein the module has a conductive material disposed in the opening of the resin film so as to cover a portion where the ground electrode and the shield film overlap.
9. The module according to claim 2 , wherein the module has a conductive material interposed between the ground electrode and the shield film in the opening of the resin film.
