Abstract
A weather strip includes an ethylene-α-olefin-nonconjugated diene copolymer rubber composition having a volume resistivity of no less than 1.0E+6 Ω·cm and having a specific gravity of less than 1.30, the rubber composition including: carbon black in an amount of 40 parts by mass to 140 parts by mass; and at least one polymer having a specific gravity of no more than 1.8 and an ethylene content of no more than 70 wt % and at least one polymer having a specific gravity of no more than 1.8 and an ethylene content of no less than 70 wt % in a collective amount of 5 parts by mass to 50 parts by mass, per 100 parts by mass of an EPDM polymer. At least a mount base of the weather strip, which is to be mounted to a car body, is formed of the rubber composition.
