Abstract: A vehicle wheel disc includes a flat plate-shaped hub-mounted part, a cylindrical rim-mounted part, and a hat-shaped part. The hat-shaped part includes a hat top portion, a hat inner peripheral portion, and a hat outer peripheral portion. At a border between the hub-mounted part and the hat inner peripheral portion, a first connecting portion is provided, and at a border between the hat top portion and the hat outer peripheral portion, a second connecting portion is provided. The plate thickness of the hat outer peripheral portion is smaller than the plate thickness of an intermediate portion that is a portion from a border between the first connecting portion and the hat inner peripheral portion to a border between the hat top portion and the second connecting portion in the disc radial direction.

Abstract: A connection structure for a wiring substrate and a flexible substrate including a wiring substrate and a flexible substrate, in which the wiring substrate includes an insulating member, conductor layer, and ground layer, the flexible substrate includes an insulating sheet and metal film, and the metal film includes a signal line pad joined to the conductor layer via a joining material when viewed from the back surface of the flexible substrate. When viewed from behind the flexible substrate, there is an overlap region where the signal line pad and conductor layer overlap. In a cross-section when the overlap region is cut in a direction perpendicular to a signal transmission direction, in a case where a width of the signal line pad including the overlap region is W, and a width of the conductor layer including the overlap region is W0, the connection structure satisfies W0<W.
