Abstract:
1. An electronic component module comprising: a first electronic component which is disposed on a top surface of a substrate; a second electronic component which has a height lower than that of the first electronic component and is disposed on the top surface of the substrate so as to be side by side with the first electronic component; a planar top plate which is fixed to the first electronic component so as to cover the first electronic component and the second electronic component; and a top plate holding member which is disposed between the second electronic component and the top plate so as to hold the top plate wherein the top plate has a composite structure including an insulating base material portion, and an electrically conductive foil formed on the base material portion, wherein the top plate further includes an insulating member which covers the electrically conductive foil, wherein the insulating member has an opening portion which exposes a part of the electrically conductive foil, and wherein the top plate is adapted so that the opening portion is disposed on the opposite side to the substrate.
