The present invention provides a block copolymer composition having a good dry state and a low odor in a drying process as a production process, and an adhesive composition containing the same. A component (a): a block copolymer having a polymer block A mainly composed of vinyl aromatic compound units and a polymer block B mainly composed of conjugated diene compound units, and component (b): It contains an organic acid having a carboxyl group and a molecular weight of less than 800 and / or a salt thereof, and the content of the vinyl aromatic compound unit in the component (a) is 10% by mass or more and 60% by mass or less, and a 15% by mass toluene solution. A block having a viscosity of 10 mPa · s or more and less than 70 mPa · s at 25 ° C. and containing 0.02 parts by mass or more and 0.3 parts by mass or less of component (b) with respect to 100 parts by mass of component (a). Copolymer composition. [Selection figure] None |
