Hydrogenated block copolymer and composition of the same
 A hydrogenated block copolymer comprising: at least two polymer blocks A mainly comprising vinylaromatic hydrocarbon compound monomer units; and at least two polymer blocks B mainly comprising hydrogenated conjugated diene compound monomer units, in which at least 90% of the olefinically unsaturated double bonds contained in the unhydrogenated polymer block mainly comprising the conjugated diene compound monomer units is hydrogenated, wherein at least one of the terminal blocks is a polymer block B, the proportion of the terminal polymer block B in the hydrogenated block copolymer being 0.1% by weight or higher and lower than 9.1% by weight, and wherein the content of the vinylaromatic hydrocarbon compound units in the hydrogenated block copolymer is 12% by weight or higher and lower than 25% by weight. Also disclosed are a resin composition containing the hydrogenated block copolymer, and a molded article of the resin composition.
