  A poly-1-butene resin composition suitable for use in a water or hot water supply pipe; a water or hot water supply pipe which is produced from the poly-1-butene resin composition and which is superior in stress crack resistance in chlorine-containing aqueous environment; and a double-pipe structure which is composed of the pipe and which is superior in stress crack resistance in chlorine-containing aqueous environment, are provided. The poly-1-butene resin composition includes a specific benzoate-based additive (A) and a specific phenol-based additive (B) being at least one selected from a phenol-based additive (B1), a phenol-based additive (B2) and a phenol-based additive (B3), wherein contents of (B1), (B2) and (B3) are each from 0.2 to 1.0 part by weight with respect to 100 parts by weight of the poly-1-butene resin; and a weight ratio of (A) to (B) is (A): (B) = 1:1.5 to 1:5.
