Abstract
A resin composition includes a resin component including an ethylene-(meth)acrylate copolymer and at least either an ethylene-propylene-diene terpolymer or ethylene acrylate rubber. A content of the ethylene-(meth)acrylate copolymer with respect to a total content of the ethylene-(meth)acrylate copolymer and at least either the ethylene-propylene-diene terpolymer or the ethylene acrylate rubber is 35% by mass or greater and 90% by mass or less. A tensile stress at 19% strain of the resin composition is 2.0 MPa or less, and a tensile stress at break of the resin composition is 10.3 MPa or greater.
