PROBLEM TO BE SOLVED: To provide an RTM molding method for efficiently manufacturing a molded article hardly having the generation of sink marks on the design surface, and to provide a die which is used for the RTM molding method. SOLUTION: When the FRP molded article 30 is manufactured by the RTM molding method using top and bottom divided type dies 10 and 20, the die in which a groove 40 in the circumferential direction (horizontal direction) is formed on at least a part on an inner side surface of the lower die 20 is used. Also, the RTM molding is performed by applying a releasing agent 20a of which the releasing force is relatively strong to the lower die 20, and applying a releasing agent 10a of which the releasing force is relatively weak to the upper die.
