PROBLEM TO BE SOLVED: To provide a method for manufacturing a reinforced concrete member, which can minimize the binding force of reinforcing bars in contraction of concrete and also the temperature difference between the inside and surface of a member in hardening of concrete, and is thus advantageous for prevention of crack with a reduced cost. SOLUTION: Reinforcing bars 12 including a plurality of main bars 14 and tie hoops 16 are arranged inside a first form K1, and high-strength concrete C is placed in the first form K1. After a predetermined curing period, the first form K1 is removed, whereby an inside portion 20 is obtained. The inside portion 20 is placed inside a second form K2, and reinforcing bars 12 including main bars 14 and tie hoops 16 are arranged around it, and high-strength concrete C is placed in the second form K2. After a predetermined curing period, the second form K2 is removed, whereby a reinforced concrete column member 10 in which an outside portion 30 is integrated to the inside portion 20 is obtained.
