A method for molding a composite material by shaping, by using a molding die, a laminate of fiber sheets including a bent portion, and curing a resin impregnated into the fiber sheets. The molding die has a molding surface and a recess other than the molding surface. The composite material molding method includes: disposing the laminate on the molding surface; covering the laminate with a tension generating member that generates tension in the laminate at shaping, and disposing a part of the tension generating member to face the recess; covering the laminate with a covering member to hermetically seal between the covering member and the molding die; sucking atmosphere between the covering member and the molding die to draw in a part of the tension generating member into the recess to shape the laminate; and curing the laminate after shaping to mold the composite material.
