PROBLEM TO BE SOLVED: To prevent the damage of an FRP layer by the compressed air blown onto the FRP layer when the cured FRP layer is demolded from a mold. SOLUTION: Air blow ports 16 are formed in the surface of a mold main body 11 and, when the cured FRP layer 30 formed on the mold main body 11 is demolded, compressed air blown out of the air blow ports 16 is blown onto the FRP layer. When compressed air is blown, the cured FRP layer 30 is pressed by the press plate 25 of a press mechanism 20 and the deformation of the FRP layer 30 by compressed air is prevented to prevent the damage of the FRP layer 30. |
