Zusammenfassung:	PURPOSE:To enlarge anchor effects, to firmly retain a pressure-sensitive adhesive layer on an expanded base, to raise air permeability by high voids and to improve bond strength to a material to be bonded by extending a fibrous pressure-sensitive adhesive on the surface of expanded base to form a pressure- sensitive adhesive layer of porous structure. CONSTITUTION:A fibrous pressure-sensitive adhesive 21 is extended on the surface of a porous expanded base 1 to form a pressure-sensitive adhesive layer 2 of porous structure. The prepared tacky member has air permeability in the extending direction of pressure-sensitive layer, excellent uniform distribution of bonding contributing point, large bond area and reduced unevenness of bond strength to expanded base and materials to be bonded.
