Claim Text:
1. An electronic component mounting structure, comprising: a three-dimensional substrate having a three dimensional shape and including a hollow portion formed on at least one of side surfaces of the three dimensional substrate the three-dimensional substrate including: a bottom face, and four wall portions forming the hollow portion, each perpendicularly connected to the bottom face: and an electronic component mounted on the bottom face of the hollow portion, wherein in at least one of the four wall portions, the three dimensional substrate includes an opening portion is formed on a side surface different from a side surface on which the hollow portion is formed for allowing observation of a connection portion between the bottom face of the hollow portion and the electronic component from an outer periphery side of the three-dimensional substrate, wherein the three-dimensional substrate includes a connection electrode on the bottom face of the hollow portion, the electronic component includes a connection terminal connected to the connection electrode, and the opening portion has a height at which each of a plane including the bottom face of the hollow portion and a plane including a surface of the electronic component opposed to the three-dimensional substrate passes through, and has a width not more than a width of the electronic component and not less than a width of the connection terminal.
