Abstract
A resin composition containing a hydrogenated block copolymer (I) and a polypropylene-based resin (II), and a molded body and a tube obtained by using the resin composition. In the resin composition, the hydrogenated block copolymer (I) includes a polymer block (A) and a polymer block (B), the polymer block (B) includes a structural unit derived from a conjugated diene compound, an average of vinyl bond amounts in the whole polymer block (B) included in the resin composition is 50% by mole or more, and a D hardness of a sheet prepared through hot-press molding of the resin composition is less than 50.
