Resin composition, coated electric wire, and wire harness

Abstract

A resin composition contains a polyolefin resin, a metal hydroxide-based flame retardant, an inorganic filler, and an antioxidant. A content of the metal hydroxide-based flame retardant is 60 parts by mass or more and 140 parts by mass or less with respect to 100 parts by mass of the polyolefin resin. The inorganic filler is formed by using zeolite and an organically modified layered silicate in combination. A content of the zeolite is 0.5 parts by mass or more and 2.0 parts by mass or less with respect to 100 parts by mass of the polyolefin resin. The zeolite has a pore diameter of 3.0 Å or more and 6.5 Å or less, or a pore diameter of more than 6.5 Å and 9.0 Å or less, and has a silica/alumina ratio of 2 or more and 10 or less. A content of the organically modified layered silicate is 1.0 part by mass or more and 14.0 parts by mass or less with respect to 100 parts by mass of the polyolefin resin.
