PURPOSE:To obtain a sandwich panel having excellent fire resistance, being strongly made in a body with a metal plate through a lath net using a phenol foam as a core material and having excellent strength, by using the phenol foam as the core material. CONSTITUTION:Payoff reels 9 are placed at the beginning end, and a pair of belt-like metal plates 3a and 3b is fed continuously on upper and lower parts face to face. Lath net feeding apparatuses 10 for feeding continuously lath net 2 are placed between the upper and lower payoff reels. A roll molding machine 11 is placed in front of the payoff reels 9. Bent pieces 17a and 17b are formed toward both edge parts of the metal plates 3a and 3b by means of the roll molding machine 11. A lath net adhering machine 12 for adhering the lath nets 2 on the metal plates 3a and 3b with epoxy and urethane thermosetting resin adhesives is placed in front of the roll molding machine 11. A pouring and foaming machine 14 for pouring a phenol resin 1a is placed in front of a preheating apparatus 13.
