The present invention relates to a modified hydrogenated product of a block copolymer having a polymer block (A) containing a structural unit derived from an aromatic vinyl compound, and a polymer block (B) containing a structural unit derived from a conjugated diene compound, a method of producing the modified hydrogenated product, and a resin composition containing the modified hydrogenated product. The modified hydrogenated product has one or more functional groups selected from an alkoxysilyl group, a carboxy group, an amino group, a hydroxy group, an epoxy group, and an acid anhydride-derived group, and satisfies the following conditions.
Condition (1): after stay at 330°C for 30 min under nitrogen atmosphere, a weight change rate is -5.5% or more.
Condition (2): the peak top intensity of tan δ measured in accordance with JIS K7244-10 (2005), under conditions including a strain amount of 0.1%, a frequency of 1 Hz, a measurement temperature of -70 to 120°C, and a temperature rise rate of 3°C/min, is 1.0 or more.
