PROBLEM TO BE SOLVED: To provide a method for producing a reinforced concrete member which is advantageous to prevent cracking while reducing costs. SOLUTION: Reinforcements 12 are arranged in a form 30, and the temperature of the arranged reinforcements 12 is elevated to generate a tensile strain by thermal expansion in the reinforcements 12. Next, concrete C is poured into the form 30 and cured in a curing tank 40. The curing includes first curing and second curing. The first curing is carried out at an expected maximum temperature while the temperature of the poured concrete C is increased gradually by the heat of hydration to reach a peak. The second curing is carried out at the temperature of the center of the cross section of the reinforced concrete member 10 which is decreased to follow the temperature of the concrete C lowering gradually after reaching the peak.
