PROBLEM TO BE SOLVED: To provide a crushing device capable of efficiently crushing a material to be crushed. SOLUTION: The crushing device 1 is structured of a fixed disc side protrusion group T' formed by implanting a plurality of fixed disc side protrusions in the diametral direction of a fixed disc 40 and a rotary disc side protrusion group T formed by implanting a plurality of rotary disc side protrusions in the diametral direction of a rotary disc 30, where the rotary disc side protrusion group T and the fixed disc side protrusion group T' are arranged so as to be staggered to each other. Thus, a fixed disc side blade part 40b and a rotary disc side blade part 30b are opposed to each other while leaving a space in between so that both do not come into contact with each other.
