Abstract: A cylinder head cover is mounted on a cylinder head of an internal combustion engine to cover a camshaft supported by the cylinder head. The cylinder head cover includes a cover main body and a baffle plate. The cover main body includes a head mounting surface to be connected to the cylinder head and a bulging portion bulging away from the cylinder head farther than the head mounting surface. The bulging portion includes a recess that is recessed to approach the head mounting surface. The recess includes a bottom wall inclined with respect to a horizontal plane in a state in which the cover main body is mounted on the internal combustion engine. The baffle plate is joined to a surface of the bulging portion facing the camshaft at least at a section corresponding to the bottom wall of the recess.
