摘要： The present invention is a polishing head in which a rubber film is formed in a boot shape in such a manner that a position where the rubber film is held by a mid plate is distantly positioned from a work holding portion; an end portion of the boot shaped rubber film is formed in O-ring shape so that the rubber film is held by the mid plate with decreasing an area of contact between the mid plate and the rubber film as much as possible. As a result, there is provided a polishing head with rubber chuck method in which an occurrence of a surface defect, such as a scratch, on a surface of the work is suppressed as much as possible and the work can be uniformly and stably polished to the outer periphery.
