Abstract: A method for producing the silica carrier which includes kneading fumed silica obtained by a combustion method, silica gel obtained by a gel method, and colloidal silica obtained by a sol-gel method or a water glass method, molding the resulting kneaded product, and calcining the resulting molded body. The silica carrier has, in the measurement of pore size distribution, mesopores with a pore size of 2 to 50 nm and macropores with a pore size of more than 50 nm and 1,000 nm or less.
