<p>A solar heat collector comprises an evacuated transparent pipe (1); a solar heat collection plate (7) disposed in the transparent pipe (1), a heat pipe (3) disposed in the transparent pipe (1) so as to contact with the solar heat collection plate (7), and containing an evaporable working liquid therein; a heat medium pipe (11) containing a heat medium to be heated; a heat releasing fin portion (131) extending from the axis to the inner surface of the heat medium pipe (11); and a cylindrical casing (9) surrounding coaxially the heat medium pipe (11) to provide an annular space (11) communicating with the heat pipe (3). The evaporable working liquid evaporates, receiving solar heat collected by the heat collection plate (7). The resultant vapor heats the heat medium through the heat medium pipe (11) and the heat releasing member (130).</p>
