To provide an automobile wheel excellent in strength relative to lateral G and traveling stability by enhancing the rigidity of a wheel disc.
A virtual inner inclination line L contacted with the respective inner peripheral surfaces 42a, 32a of an inner recessed peripheral part 42 of a hat 24 and the hub surface rounded part 32 of a hub mounting part 21, and a virtual outer inclination line N passing through the intersection G of a virtual bottom line M along the back surface of the hub mounting part 21 with a disc flange 25 and contacted with an inner peripheral surface 44a of an outer recessed peripheral part 44 of the hat part 24 are determined such that a ratio of a virtual inner inclination angle α and a virtual outer inclination angle β relative to the virtual bottom line M is set to 0.8-1.25. It is determined such that a separation distance t in a radial direction of a virtual intersection P of the virtual inner inclination line L and the virtual outer inclination line, and an apex O of a hat apex peripheral part of the hat 21 is set to 2.5 mm or less.
