Hydrogenated copolymer, resin composition, molded article, and adhesive film

A hydrogenated copolymer (X) comprising:

• a hydrogenated copolymer (A) which is a hydrogenated copolymer of a vinyl aromatic monomer unit and a conjugated diene monomer unit;
• and
• a hydrogenated copolymer (B) which is a hydrogenated copolymer of a vinyl aromatic monomer unit and a conjugated diene monomer unit, the hydrogenated copolymer (B) has at least one polymer block mainly comprising a vinyl aromatic monomer unit, wherein
• the hydrogenated copolymer (X) satisfies the following requirements (1) to (4):
• (1):
• the hydrogenated copolymer (A) has a random copolymer structure comprising a conjugated diene monomer unit and a vinyl aromatic monomer unit, and a content of the vinyl aromatic monomer unit in the hydrogenated copolymer (A) is 10 mass % or more and 80 mass % or less;
• (2):
• the hydrogenated copolymer (B) has a random copolymer structure comprising a conjugated diene monomer unit and a vinyl aromatic monomer unit, and a content of the vinyl aromatic monomer unit in the hydrogenated copolymer (B) is 10 mass % or more and 80 mass % or less;
• (3):
• a ratio (Mn1/Mn2) of a number-average molecular weight (Mn1) of the hydrogenated copolymer (A) to a number-average molecular weight (Mn2) of the hydrogenated copolymer (B) is less than 0.25, and 1000≤Mn1≤40000;
• and
• (4):
• a mass ratio (A)/(B) of a content of the hydrogenated copolymer (A) to a content of the hydrogenated copolymer (B) is 5/95 to 50/50.
