Abstract
A resin composition, including: a resin component containing propylene units, and a resistance-imparting agent, wherein the resistance-imparting agent is a monomer having a phenol skeleton with hydrogen or an alkyl group having 1 to 3 carbon atoms, bonded to at least one of ortho positions to the hydroxyl group of the phenol skeleton, and has a melting point of 215° C. or less and a molecular weight of 200 or more and 500 or less, a content of the resistance-imparting agent is 0.4 parts by mass or more and 10 parts by mass or less with respect to 100 parts by mass of the resin component, and a content ratio of metal impurities is 0.02% by volume or less.

A resin composition, comprising:
- a resin component containing propylene units, and
- a resistance-imparting agent,
- wherein the resin component comprises a propylene-based resin and a flexible component containing a low-crystallinity resin and a styrene-based resin,
- wherein the low-crystallinity resin is a copolymer obtained by copolymerization of at least any two of ethylene, propylene, butene, hexene, and octene, and has no melting point or has a melting point of 100° C. or less,
- wherein the resistance-imparting agent is a monomer having a phenol skeleton with hydrogen or an alkyl group having 1 to 3 carbon atoms, bonded to at least one of ortho positions to the hydroxyl group of the phenol skeleton, and has a melting point of 215° C. or less and a molecular weight of 200 or more and 500 or less,
- a content of the resistance-imparting agent is 0.4 parts by mass or more and 10 parts by mass or less with respect to 100 parts by mass of the resin component, and
