<P>PROBLEM TO BE SOLVED: To provide a film mirror having a higher reflectance than a conventional film mirror and higher durability and anti fouling property, and to provide a film mirror for condensing solar light that maintains thermal power generation efficiency for a long term when the film mirror is used in a reflector for solar thermal power generation device. <P>SOLUTION: The film mirror comprises a metal reflection layer on a resin substrate, and does not include a layer formed by laminating resin films on the metal reflection film at a light incident side, but includes an inorganic gas barrier film instead. <P>COPYRIGHT: (C)2012,JPO&INPIT |
