To enable suction holding without damaging the front surface by detachably mounting a protective sheet made of a soft member on the suction surface side of an suction pad.

In the suction pad, a negative pressure port 32 communicated with a vacuum pump is provided in the center part on an suction surface 31 side, a plurality of projecting parts 33 are concentricity formed on the suction surface 31 side, and negative pressure passage 33a are provided between the projecting parts 33 so that the negative pressure port 32 may not be closed when matters to be sucked are stuck on the suction surface 31 side. A soft part flap 34 whose tip is thin wall is provided in order to prevent air from entering the suction pad lower part peripheral edge from the outside, and a flay surface part is provided on the inner surface. A protective sheet 40 covers the front surfaces of the projecting parts 33, formed on a soft member such as rubber sponge, soft plastic, etc., into a foldable thin plate shape, and communicated with the negative pressure port 32 by a suction hole 41, the outside diameter is smaller than that of the pad, and the protective sheet is detachably attached to the flat surface part by adhesive pieces 43. Therefore, the front surface of the article to be sucked is not damaged.
