摘要
Provided are a wet friction plate configured so that drag torque can be reduced while a manufacturing burden is reduced with a simple configuration, a wet multiplate clutch device including the wet friction plates, and a wet friction plate manufacturing method. A wet friction plate (200) includes friction members (210) provided on a flat plate annular core metal (201), having oil grooves (203), and made of a paper material. The friction members (210) include higher friction members (211) and lower friction members (212). The higher friction member (211) is formed such that the height thereof from a surface of the core metal (201) is higher than that of the lower friction member (212). In addition, the higher friction member (211) is formed with a less-elastically-deformable structure than that of the lower friction member (212). The lower friction member (212) is formed such that the height thereof from the surface of the core metal (201) is lower than that of the higher friction member (211). In addition, the lower friction member (212) is formed with a more-elastically-deformable structure than that of the higher friction member (211). The higher friction members (211) and the lower friction members (212) are alternately arranged along a circumferential direction on the core metal (201).
