Abstract
A drum patch formed into a sheet shape is adhered to a hitting surface of a drum. Since a first slit and a second slit extending toward a hit region are formed at the outer edge of the drum patch, relatively flexible deformation is possible at the outer edge portion. Accordingly, the slits can absorb deformation in which the outer edge portion of the drum patch rises from the hitting surface when hitting the hit region. Thus, peeling of the drum patch from the hitting surface can be suppressed.
