Abstract
A halogen-free crosslinked resin composition includes a base polymer including as a main component (a) an ethylene vinyl acetate copolymer and (b) an acid modified polyolefin resin having a differential scanning calorimetry glass transition temperature Tg of not higher than −55 degrees Celsius in a mass ratio (a):(b) of 70:30 to 100:0, the base polymer including 50 to 70% by mass of vinyl acetate, 0.5 to 10 parts by mass of a silicone rubber with respect to 100 parts by mass of the base polymer, and 100 to 250 parts by mass of a metal hydroxide with respect to 100 parts by mass of the base polymer.
