PROBLEM TO BE SOLVED: To provide a profile measuring device which can measure the shape of the circumferential face of an object with ease and accuracy, and to provide a circumferential face measuring method. SOLUTION: The profile measuring device 1, which measures the shape of the circumferential face of a main journal 3, comprises a measuring member 15 which consists of probes 16, 17, and 18 which see from an axial direction and accomplish an angle of 120°; a gauge head coordinate information acquiring section 21a which acquires coordinate informations 31, 32, and 33, when moving probes 16, 17, and 18 that contact a first measuring area 3a; a second measuring area 3b, and a third measuring area 3c which a central angle seen from an axial direction in the circumferential face of a main journal 3, is larger than 120°, as well as both the ends overlap mutually; a duplicate coordinate information cutout 21b which deletes a feature which overlaps others and measuring area among coordinate information 31, 32, and 33; and a subject shape information creation section 21c which connects coordinate informations 31c, 32c, and 33c after being deleted, and creates the shape information of the circumferential face of the main journal 3.
