Abstract
A friction plate for a wet type multiplate clutch has a substantially ring-shaped core plate and a friction member attached to the core plate. The friction member has a surface which includes a passage formed on a surface of the friction member, the passage extending from an inner peripheral edge of the friction member to an outer peripheral edge of the friction member, and a groove having an opened end which opens to the inner peripheral edge of the friction member and a closed end which is closed at a middle of the surface of the friction member. A width of the groove decreases towards a direction to the outer peripheral edge from the inner peripheral edge of the friction member.
