To save material for a disc and reduce the weight.

In an automotive wheel in which a disc 10 and a rim are welding to be joined, and in its manufacturing method, the dimension L of a side of a nearly square row material 41 for the disc is determined so that the most recessed part 12 of ventilation 11 of the disc 10 is deviated outward 5mm or more from the center 24 of round corner part 23 extending from a drop part 21 of the rim 20 to the side wall part 22 in the axial direction of the wheel. However, the wheel-circumferential length of the end part of a riser part 13 of the disc must be 30mm or more.
