16 Claims

1. A gel composition, comprising:

a base oil and

a hydrogenated block copolymer,

wherein the hydrogenated block copolymer is a hydrogenated product of a diblock copolymer composed of a first polymer block consisting of a structural unit derived from an aromatic vinyl compound in an amount of 50% by mass or more based on the total mass of the first polymer block, and a second polymer block consisting of a structural unit derived from isoprene in an amount of 50% by mass or more based on the total mass of the second polymer block,

the content of the first polymer block in the hydrogenated block copolymer being from 38.0 to 45.0% by mass,

the content of a vinyl bond structural unit in the second polymer block is from 2 to 10 mol %, and

the content of the hydrogenated block copolymer in the gel composition is from 1 to 20 parts by mass based on 100 parts by mass of the total amount of the base oil and the hydrogenated block copolymer.
