By heating, the decorative plate is internally bent to form the vertical portion (4). During this internal bending, the floating portion (10) of the adhesive bond caused by heating can be minimized by the action of the groove on the back surface of the decorative plate. Next, fix the fixing material (11) to the horizontal part (1
2) and the vertical portion (4) are temporarily fixed or adhered. Next, a synthetic resin is injected into the space (13) surrounded by the decorative plate, the core material and the fixing material and cured to form the resin layer (6).

る。As described above, according to the inward bending method of the present invention, the decorative plate and the core material are bonded together in a flat state, so that the decorative plate does not wrinkle. Further, since the groove portion provided on the core member is located at the bending position of the decorative plate, the dimension of the vertical portion (4) can be arbitrarily set. Further, since the synthetic resin is injected into the inner bent corners and hardened, there is no gap between the decorative plate and the core material, and the inner bent product is excellent in strength.
