a content of the polyether compound having a cationic group is 0.1 to 30 parts by weight based on a total of 100 parts by weight of the resin and the rubber.

### Claim 2 (depends on 1)

A formed product obtained by forming the composition for a formed product according to claim 1.

### Claim 3

A cross-linkable composition
wherein the cross-linkable composition is a blend of an anti-static agent containing a polyether compound having a cationic group, a resin and/or rubber, and a cross-linking agent formed by blending the anti-static agent, the resin and/or rubber and the cross-linking agent, wherein
a content of the polyether compound having a cationic group is 0.1 to 30 parts by weight based on a total of 100 parts by weight of the resin and the rubber.
