PROBLEM TO BE SOLVED: To provide an end measuring device for pipe body capable of efficiently measuring the dimension between 2 points connecting the inner surface beveled tips of a pipe body. SOLUTION: A straightedge 4 is provided with a protrusion 3 having an angleβlarger than a bevel angleαof an inner surface beveled portion 2. And, an end measuring device comprises a scale 5 attached to both ends of the straightedge 4 so that a base end (a) on the large angleβside of the protrusion 3 is a reference point (0 point). When a tip inner diameter L of the inner surface beveled portion 2 is measured, the straightedge 4 is brought into contact with a pipe end so as to bring the base end (a) on the large angleβside of the protrusion 3 provided for the straightedge 4 into contact with a tip of the inner surface beveled portion 2, and read the scale 5 corresponding to a the tip on the opposed side and the root face 6 dimension.
