Abstract
Disclosed herein is a suction pad for attracting and holding a work, which comprises a suction base coupled via a connector to a vacuum suction source, a suction skirt integrally provided in continuation with the base, and a vacuum chamber which is defined inside the suction pad and communicates with the inside of the skirt. In addition, the suction pad includes a plurality of smaller-diameter through holes which cause the vacuum chamber to communicate with a suction surface of the skirt, and partition walls for surrounding the through holes. The partition walls define a number of small vacuum chambers.
