1. A resin composition, characterized in that it contains a multi-component copolymer, the multi-component copolymer comprising a non-conjugated olefin unit, a conjugated diene unit, and an aromatic vinyl unit, characterized in that:
a ratio [(C100-120/C0-100) ×100] of crystallinity (C100-120) derived from the non-conjugated olefin unit at 100-120° C. with respect to crystallinity (C0-100) derived from the non-conjugated olefin unit at 0-100° C., as measured by a differential scanning calorimeter (DSC), is 23% or less.
