Abstract: A milling cutter (100) comprising: a cartridge (33) that has a tip (32) fixed thereto; a body (10) that has a pocket (15) formed therein into which the cartridge (33) is inserted; and a fixing tool (40) that fixes the cartridge (33), wherein the body (10) has a fixing tool insertion hole (16) that is adjacent to the pocket (15) on the radial direction inner side thereof, and a partitioning wall (17) between the pocket (15) and the fixing tool insertion hole (16), the fixing tool (40) that has been inserted into the fixing tool insertion hole (16) exerts a radial direction outward force on the partitioning wall (17), the pocket (15) is formed so as to produce a counterforce that resists the radial direction outward force acting on the cartridge (33) via the partitioning wall (17), and the cartridge (33) is fixed in the pocket (15) on the basis of the radial direction outward force.
