An automobile sandwich glass capable of realizing uniform electric heating for a windshield wiper resting position is disclosed. The automobile sandwich glass comprises two glass substrates (4) and a middle electric heating coating layer sandwiched between the two glass substrates (4); three busbars are distributed in the middle electric heating coating layer; a third busbar (3) is arranged between a first busbar (1) and a second busbar (2); the electric heating coating layer is divided into two regions by the third busbar (3); the region between the first busbar (1) and the third busbar (3) is a visual area heating region; and a windshield wiper resting position heating region (5) is between the second busbar (2) and the third busbar (3). The automobile sandwich glass has the advantages that 1, effective heating for the main visual region of the foreside windscreen of the automobile is ensured, and the effective heating for the windshield wiper resting position is ensured as well; 2, the two heating regions are powered by the same voltage; 3, overheating in the heating process for the windshield wiper resting position is prevented; and 4, uniform heating for the windshield wiper resting position is realized.
