PURPOSE: To obtain a sheet capable of uniformly sticking to an object of sticking without any remaining air between a tacky sheet and an object of tack by laminating a release sheet having a releasable surface with unevennesses capable of making a gas communicate throughout the whole surface thereof to a tacky surface.
CONSTITUTION: This sheet is obtained by forming releasable sheets 2 and 5 having unevennesses of an optional shape, having 50-1000μm (preferably 100-800μm) protruding width and 10-1000μm (preferably 20-1000μm) protruding height and capable of making a gas communicate throughout the whole surface to a film 1 having one or both tacky surfaces and thereby forming the unevennesses corresponding to those of the releasable sheets 2 and 5 in the tacky surface of the tacky film 1.
