A mounting structure in which a photovoltaic element is mounted together with a metal body for outputting a power generated by said photovoltaic element to the outside, said photovoltaic element having a light receiving face and a non-light receiving face and having a pair of electrodes on said non-light receiving faces said metal body having a first surface and a second surface opposite said first surface, wherein said photovoltaic element is joined to said first surface of said metal body and an electrically insulative joining material is joined to said second surface of said metal body. A semiconductor element-mounting substrate for mounting a semiconductor element thereon, said mounting substrate comprising a retaining substrate having a circuit pattern for said semiconductor element, said circuit pattern having an electrode-joining portion for joining an electrode portion of said semiconductor element and an external terminal-fixing portion for fixing an external terminal and a groove being provided between said electrode-joining portion and said external terminal-fixing portion.
