A masterbatch is disclosed including a sulfide compound (A) and filler (B). The sulfide compound (A) is a chain or cyclic compound of repeating units represented by; R—Sx (I);where R represents a linear, branched or cyclic alkylene group having 1 to 12 carbon atoms; a linear, branched or cyclic (poly)oxyalkylene group having 1 to 12 carbon atoms; or a linear, branched or cyclic (poly)thioalkylene group having 1 to 12 carbon atoms (wherein the alkylene group, the (poly)oxyalkylene group and the (poly)thioalkylene group are unsubstituted or have 1 or more optional substituents), and x represents an integer from 1 to 8. The filler (B) is at least one selected from the group consisting of carbon black, talc, clay, mica, sericite, diatomaceous earth, zinc white, and organic resin particles and satisfies following conditions that BET specific surface area is 0.1 to 200 m2/g and DBP oil absorption is 50 to 300 ml/100 g.
