Abstract
A solar heat collector includes a plurality of heat collecting tubes connected in series. The heat collecting tubes each include: a heating-medium circulating tube through which a heating medium circulates; a glass tube that covers an outer peripheral surface of the heating-medium circulating tube and forms an annular space between the glass tube and the heating-medium circulating tube; and a getter member that adsorbs a gas that exists within the annular space. The heat collecting tube on a downstream side of the heating medium includes a larger number of the getter members than the heat collecting tube on an upstream side of the heating medium.
