Abstract
An adsorption temporary fixing material comprises an adsorption temporary fixing sheet including a foam layer having an open-cell structure, wherein the adsorption temporary fixing material includes the foam layer in the entirety of the sheet or on at least one surface thereof, wherein a shear adhesive strength of a surface of the foam layer with a SUS304BA plate at 23° C. is 1 N/100 mm2 or more at a tensile rate of 50 mm/min, wherein a peel strength of the surface of the foam layer from the SUS304BA plate at 23° C. is 1 N/20 mm or less at a peel angle of 180° and a tensile rate of 300 mm/min, and wherein a weight change ratio after the adsorption temporary fixing sheet has been immersed in distilled water for 1 minute and then water droplets have been wiped off the surface thereof is 50% or less.
