Abstract
A clutch plate in an annular shape, the clutch plate includes: a plurality of lubricating grooves on one end face and the other end face of the clutch plate in an axial direction; and a plurality of windows passing through the clutch plate in the axial direction. The lubricating grooves are formed with plastic deformation, in a same phase on both the end faces, and extended up to outer peripheral edges and inner peripheral edges of both the end faces. A plurality of intersection points where the lubricating grooves intersect with each other are positioned in other areas than at least one of the outer peripheral edges, radially outer edges of the windows, radially inner edges of the windows, and the inner peripheral edges, of both the end faces.
