To provide a heat-absorbing glass plate which satisfies both low solar transmittance and high visible light transmittance, the transmitted light through which is green, and which contains a small number of coloring components. A heat-absorbing glass plate which comprises soda lime silica glass containing coloring components, the coloring components containing, as represented by mass% based on the following oxides, from 0.45 to 0.61% of total iron as calculated as Fe 2 O 3 and from 0.2 to 0.6% of TiO 2 , which contains substantially no CoO, Cr 2 O 3 , V 2 O 5 , MnO nor CeO 2 , which has a mass proportion of bivalent iron as calculated as Fe 2 O 3 in total iron as calculated as Fe 2 O 3 of from 45 to 60%, which has a solar transmittance of at most 42% calculated as 4 mm thickness, which has a visible light transmittance (by illuminant A) of at least 70% calculated as 4 mm thickness, and which provides a transmitted light having a dominant wavelength of from 492 to 500 nm.
