PROBLEM TO BE SOLVED: To provide a resin composition which not only is excellent in mechanical properties such as softness, tensile strength, elongation and compression set, but also exhibits excellent adhesiveness with an olefinic resin and the like, by compounding an olefinic resin, an ethylene-α-olefin copolymer rubber, a hydrogenated aromatic vinyl compound -conjugated diene compound block copolymer rubber and a mineral oil. SOLUTION: This resin composition for use in adhering comprises (A) 5 to 50 pts.wt. olefinic resin, (B) 5 to 86 pts.wt. ethylene-α-olefin copolymer rubber, (C) 2 to 30 pts.wt. hydrogenated aromatic vinyl compound -conjugated diene compound block copolymer rubber, (D) 2 to 40 pts.wt. at least one rubber selected from the group consisting of natural rubber, isoprene rubber and butadiene rubber and (E) 5 to 80 pts.wt. mineral oil. The composition may further comprise calcium carbonate in an amount of 2 to 50 pts.wt. relative to 100 pts.wt. of the total amount of A to E. Polypropylene and propylene are preferably employed as A andα-olefin in B, respectively.
