Abstract
A sucking and holding device includes: a vacuum chuck for vacuum-sucking a substrate; and a suction assisting device for sandwiching the object between it and the vacuum chuck. The suction assisting device includes a substrate-facing surface. The substrate-facing surface seals a through hole provided in the substrate. With this configuration, the sucking and holding device can vacuum-suck and hold the substrate having a through hole. This leads to an accomplishment of a device which can hold various objects without positional displacement.
