Provided is a wet friction plate which can realize a further reduction of drag torque while suppressing a decrease in the total area of frictional sheets. A clutch friction plate 200 is formed by providing frictional sheets 210 and oil grooves 220 on a flat annular metal core 201. On a side surface of the metal core 201 facing a clutch plate 103, a plurality of small frictional sheets 210 and oil grooves 220 are alternatingly arranged along the circumferential direction of the metal core 201. The frictional sheets 210 are disposed to form frictional-sheet groups 211 each including five frictional sheets 210 disposed successively. Outer and inner peripheral edges 213 and 214 of the frictional sheets 210 of each frictional-sheet group 211 form continuously changing arcuate contours 213a and 214a such that the distances L213 and L214 between the outer and inner peripheral edges 213 and 214 and the center of rotation O of the metal core 201 continuously change.
