Namely, it is made 10mum or more in its depth D, and has the depth being the same or less as the plate thickness of the metal plate. In the case where the depth D is 10mum or less, the improved effect of damping properties is small, and in the case where the depth is made the same or more as the plate thickness of the metal plate, the improved effects of peel strength and damping properties or the like may be saturated, and thus it becomes disadvantageous in its cost. Accordingly, the peel strength and damping properties can be improved thereby.
