PANEL AND PANEL INSTALLATION STRUCTURE

The present invention provides a panel having a light-absorbing heat-storing panel body in which the problem of heat storage with light absorption by the panel body is reduced. A panel 51A includes a panel body 52A made of a thermoplastic resin and having light transmissivity and the light-absorbing heat-storing property of absorbing light, converting the light to heat, and storing the heat therein. The panel body 52A has a laminated structure including a light-transmissive first layer 2a and a light-transmissive second layer 2b laminated on the first layer 2a and having the higher light-absorbing heat-storing property than the first layer 2a. The light-absorbing heat-storing panel body 52A has a laminated structure including at least two layers of the layer 2b that contributes to IR absorption and the layer 2a that serves as a heat-insulating layer so that radiation of the heat stored due to IR absorption by the layer 2b contributing to IR absorption can be shielded by the heat-insulating layer 2a, and thus a temperature rise due to radiant heat from the panel body 52A can be prevented.
