Abstract
A method punches a damper out from a damper material that is detachably attached on a flexible exfoliative member through an attaching surface of the damper material with use of a hollow punch. The method includes steps of setting the damper material on a supporting surface, positioning a projection part between the exfoliative member and the supporting surface, and punching the damper out from the damper material by cutting the damper material around the projection part by the hollow punch without punching the exfoliative member.
