PROBLEM TO BE SOLVED: To provide an injection molding material for manufacturing a porous ceramic, having excellent flowability when injection-molded, and generating hardly a crack when degreased and when fired.SOLUTION: This injection molding material is obtained by mixing silica powder having 20 μm of average particle size, a polyethylene gylcol and a paraffin wax at 80:10:10 of weight ratio, and then kneading at 120°C for 3 hours, and has 115 Pa of yield stress at 80°C, which is found by executing stress sweep evaluation using a rheometer.
