PROBLEM TO BE SOLVED: To provide a hose joint that reduces manufacturing cost by omitting a step of forming a thin and long groove.SOLUTION: The hose joint 1 includes a joint body 2 with a through-hole 2b for forming a fluid passage 7, and a sleeve 15 to be fitted to the outer periphery of a distal end of the hose 11. On an end face 2c on the hose-connection side of the joint body 2, a protruding core metal part 10 is formed to be fitted to the inner periphery of the distal end of the hose 11 and including the through-hole 2b. The hose joint 1 includes a circular member 3 and a tightening nut 5. The circular member 3 is screwed to the outer periphery of a base end 12 of the core metal part 10, and allows the core metal part 10 and the distal end of the hose 11 to pass through. The tightening nut 5 is screwed to the outer periphery of the circular member 3 to reduce the diameter of the sleeve 15, and compresses the distal end of the hose 11 with the core metal part 10 and the sleeve 15.
