PROBLEM TO BE SOLVED: To provide a molding method by a VaRTM method capable of surely preventing non-impregnation of a resin with a simple structure.SOLUTION: There is provided a molding method by a VaRTM method for impregnating a resin in a vacuum state, with respect to a workpiece 11 on which a channel resistance or plate thickness is not constant. A permeation sheet which transmits only gas, and does not transmit the resin (liquid), is arranged on a bottom face of the workpiece 11 so as to contain whole length of a direction, where the channel resistance or the plate thickness of the workpiece 11 is varied, then resin is impregnated.SELECTED DRAWING: Figure 1 |
