A friction plate has a plurality of friction material segments circularly fixed on an annular core plate, wherein each of the friction material segments includes an oil groove having an opening that opens in the direction of an outer circumferential edge of the friction plate and an end portion that ends between an inner circumferential edge and the outer circumferential edge, oil passages in communication in the direction of the inner and the outer circumferential edges of the friction plate are provided among the friction material segments, and at least some of the oil passages have a first shape, the width of which in a circumferential direction decreases from the inner circumferential edge of the friction plate toward the outer circumferential edge thereof.
