To provide a thermoplastic polymer composition, which can be adhered to a synthetic resin, a ceramic or a metal without performing a primer treatment or the like, is able to be handled as a molded article, exhibits an excellent adhesive property in a broad temperature range from a low temperature to room temperature and flexibility, and has high thermal creep resistance, and a molded article using the thermoplastic polymer composition. A thermoplastic polymer composition, which contains from 10 to 100 parts by weight of a polar group-containing polypropylene-based resin (B) based on 100 parts by weight of a hydrogenated block copolymer (A) in which block copolymer containing a polymer block (S) including an aromatic vinyl compound unit and a polymer block (D) including a conjugated diene compound unit is hydrogenated, nin which the hydrogenated block copolymer (A) is a mixture containing a hydrogenated block copolymer (A1) having at least one tan ´ local maximum value in a range from -60 to -40°C, in which a block copolymer represented by formula (i) or (ii) shown below is hydrogenated: n(i)(S-D) n n(ii)(D-S) n -D n(in the formulae above, S is a polymer block including an aromatic vinyl compound unit, D is a polymer block including a conjugated diene compound unit, and n is an integer from 1 to 5); and a hydrogenated block copolymer (A2) in which a block copolymer represented by formula (iii) shown below is hydrogenated: n(iii)(S-D) m -S n(in the formula above, S is a polymer block including an aromatic vinyl compound unit, D is a polymer block including a conjugated diene compound unit, and m is an integer from 1 to 5); and a weight ratio of the hydrogenated block copolymer (A1) to the hydrogenated block copolymer (A2) is from 20:80 to 99:1. |
