PROBLEM TO BE SOLVED: To provide a propylene copolymer excellent in the balance of the physical properties of elastic modulus, rigidity, adhesiveness and so on. SOLUTION: The hydroxyl group-containing propylene copolymer contains 99.8-99.99 mol% of propylene units of structural formula (I), 0.01-0.1 mol% of polar units of structural formula (II) and 0-0.1 mol% of nonpolar units of structural formula (III) and has a weight-average molecular weight Mw of 70,000-1,000,000.
