PROBLEM TO BE SOLVED: To provide an inspection gauge for a pipe hub which permits easily and surely the inspection of a pipe hub with a simple process. SOLUTION: Reticles 31, 32, 33 for hub length inspection which show the reference position of a hub aperture end 23 when the tip of a hub length measuring body 11 abuts against a hub inner end 22 are installed on the outer surface of the measuring body 11 which is inserted in the pipe hub 21. A hub inner diameter measuring body 12 whose outer periphery is a tapered surface 17 is slidably installed on the outer periphery of the hub length measuring body. Reticles 41, 42, 43 for inner diameter inspection which show the reference position of the hub aperture end which abuts against the tapered surface when the hub inner diameter measuring body is inserted in the hub are installed on the tapered surface.
