Adhesive composition and production method for adhesive composition

Abstract

It is provided an adhesive composition having a high biobased content and having a moderate adhesive property and high heat resistance and a method for producing the same, and an adhesive composition including: a block copolymer (X) including a polymer block (A) containing a structural unit derived from an aromatic vinyl compound and a polymer block (B) containing a structural unit derived from a conjugated diene compound, and a tackifier (Y), in which the block copolymer (X) includes, as the polymer block (B), at least one polymer block (B-1) containing a structural unit derived from β-farnesene, and the block copolymer (X) include at least one selected from the group consisting of an unhydrogenated block copolymer (X0) which is a block copolymer that is not hydrogenated, and a hydrogenated block copolymer (X1) which is a hydrogenated block copolymer and has a degree of hydrogenation of less than 50 mol %.
