PURPOSE:To obtain a heat collector excellent in reflecting properties, durability and reliability, by coating a galvanized steel plate or the like with a coating material comprising metallic particulates having favorable reflecting properties for solar rays. CONSTITUTION:The reflecting plate 1 for the solar heat collector is produced by using an inexpensive material such as an aluminum-treated steel plate or a plastic plate as the galvanized steel plate or the like and coating the plate with a coating material comprising particulates of at least one metal (e.g., aluminum, copper, brass) having favorable reflecting properties for the solar rays and a binder. Accordingly, a heat collector excellent in reflecting properties and ensuring durability and reliability can be obtained. |
