PROBLEM TO BE SOLVED: To enable the suppression of a visible light transmittance within a moderate range and retention of a film resistance value high by forming a specific heat ray shielding film on the surface of a glass plate. SOLUTION: This heat ray shielding glass is obtained by carrying out the sputtering on the surface of a glass plate having <=15% visible light reflectance in an atmosphere containing nitrogen and oxygen by using a target containing a transition metal of chromium or nickel and silicon and forming a heat ray shielding film containing the silicon and/or oxygen in a nitrogen compound of chromium or a nitrogen compound of nickel having >=100kΩ/square value of surface resistivity and has 20-60% visible light transmittance. A protecting film, comprising tantalum oxide or zirconium oxide and having 5-20nm thickness is then formed on the heat ray shielding film.
