laminated thereon and heated and pressurized by the upper die 16 b to form the resin composite formed product with a product shape and the surface resin layer further the pressurizing at a strong pressure using the mold may be employed in place of pressing using the roller type press 11 for producing the composite material 30 or 30 u2032 and forcible pressurization by passing the materials through multi step rollers and cooling may be repeated to cure the binder resin and produce the composite material 30 or 30 u2032 further in the above mentioned embodiment the composite material 30 or 30 u2032 is produced and then crushed to produce the resin composite formed product however discarded composite wood and resin composite formed products may be recovered and the composite wood may be extracted to use it as a raw material for producing the resin composite formed product fig7 shows the fifth embodiment and it is an example using a hydrated metal compound as a raw material for the composite material in the case the resin composite formed product of this embodiment is produced a hydrated metal compound for example aluminum hydroxide or magnesium hydroxide is made ready the hydrated metal compound having an average outer diameter of 10 u03bcm to.
