Abstract: The present invention is a hydrogenated block copolymer obtained by hydrogenating a block copolymer [C] that comprises polymer blocks [A] and polymer block [B], a ratio (wA:wB) of a weight fraction wA of the polymer blocks [A] and a weight fraction wB of the polymer block [B] in the block copolymer [C] being 45:55 to 65:35, a ratio (w[IB]:w[IIB]) of a weight fraction w[IB] of the repeating unit [I] derived from an aromatic vinyl compound and a weight fraction w[IIB] of the repeating unit [II] derived from a linear conjugated diene compound in the polymer block [B] being 40:60 to 55:45, 90% of more of unsaturated bonds included in the block copolymer [C] having been hydrogenated, a weight average molecular weight of 60,000 to 150,000, a low-temperature-side glass transition temperature [Tg1] of 0° C. or more and a high-temperature-side glass transition temperature [Tg2] of 135° C. or more, and a stretched film.
