To effectively utilize thinning wood materials as a wood in a composite glued laminated lumber of bamboo and wood.

A bamboo glued laminated sheet prepared by arranging a plurality of sheets of bamboo materials each formed into a slender plate by cross-cut-sawing or rip-sawing Mousouchiku (a thick stemmed bamboo) of five years from its coming-up in the width direction and bonding them, and woods prepared by forming the thinning wood materials into slender plates are laminated, and they are stuck together with an adhesive containing no chemical substance harmful to the human body to form the composite glued laminated lumber. It is also formed by surrounding the outer periphery of the wood material manufactured from the thinning wood materials with the bamboo glued laminated sheets prepared by arranging a plurality of sheets of the bamboo materials each formed into a slender plate by cross-cut-sawing or rip-sawing Mousouchiku of fifth year from growing in the width direction and bonding them, and sticking the wood material and the bamboo glued laminated sheet with the adhesive containing no chemical substance harmful to the human body.
