PROBLEM TO BE SOLVED: To provide a vehicle window glass including a whole-surface deicer for defrosting and a wiper deicer for deicing wiper blades, and capable of reducing the occurrence frequency of glass breaking without degrading the deicing capability of the wiper deicer even if a large heat release value is set for ensuring the sufficient deicing capability of the wiper deicer.SOLUTION: Anode bus bars 11 to 13 of whole-surface deicers 1 to 3 are arranged at positions deviated downward of a heating portion 21 of a wiper deicer 20 and hot wire regions H1 to H3 are expanded downward, thereby arranging the heating portion 21 of the wiper deicer 20 within the hot wire regions H1 to H3. With this arrangement, heat generated from the whole-surface deicers 1 to 3 can be used to deice wiper blades B, and the heat generated from the heating portion 21 is reduced accordingly to reduce a heat stress to be generated, thereby reducing occurrence frequency of glass breaking. |
