- the vacuum gauge 41b is provided in the vacuum suction medium 27, the vacuum gauge 41b is provided at the position of the vacuum suction medium 27 corresponding to the part (for example, the thick portion 1a) where the impregnation of the resin 4 into the laminate 3 is the slowest. preferable.
- the vacuum degree in the bagging film 12 can be measured by the vacuum gauge 41.
- the arrangement relationship between the resin supply unit 13 and the deaeration waterproof unit 15 shown in FIGS. 1 and 6 is not particularly limited, and the deaeration waterproof unit 15 is arranged on the molding surface 21 side and the length of the laminate 3 It suffices if it is provided over the direction and the laminate 4 can be suitably impregnated with the resin 4. For this reason, as an example, while providing the resin supply part 13 in the bagging film 12 side of the laminated body 3 and providing it on both sides of the laminated body 3 in the width direction, the deaeration waterproof part 15 is provided on the molding surface 21 side of the laminated body 3. And may be provided at the center in the width direction of the laminate 3.
