PROBLEM TO BE SOLVED: To obtain the subject composition aiming at the light weight of the laminated insulation layer, increasing the insulating performance and enabling the increase of an adhesion strength by simultaneously using calcium silicate fine powder and a zeolite as a new blended raw material. SOLUTION: This inorganic-based adhesive composition consists of (A) 5-30 pts.wt. colloidal silica, (B) 5-40 pts.wt. calcium silicate fine powder, (C) 40-70 pts.wt. clay mineral material powder such as a kaolin and a bentonite and (D) 2-20 pts.wt. zeolite, and 90-200 pts.wt. water based on 100 pts.wt. total of the above materials. Further, it is preferable to use e.g. as the component (B), a wollastenite and a calcium silicate fine powder obtained by crushing a wasted material containing glass fibers having approximately 45μm whole surface.
