PROBLEM TO BE SOLVED: To provide an adhesion structure of a corrugated fiberboard product with good workability and capable of surely improving an adhesive strength. SOLUTION: The adhesion structure of a corrugated fiberboard product is made of a sheet of corrugated fiberboard 1 having front and rear liners 2 and 3 and a corrugating medium 4 provided between the liners 2 and 3 for sticking first adhesive faces (inner flaps 13A-14B) and second adhesive faces (outer flaps 15A-16B) via an adhesive. A plurality of small pores 18 are provided on the liner (3) on an adhesive side of at least one of the first and second adhesive faces (outer flaps 15A-16B). In addition, the adhesive (thermally fusable resin) with viscosity when not adhered is used to stick the first adhesive faces with the second adhesive faces while the adhesive enters from the small pores 18 and granularly solidifies inside.
