PROBLEM TO BE SOLVED: To provide an inclination measuring instrument capable of more accurately measuring the inclination of a measuring object. SOLUTION: The inclination measuring instrument is provided with a measuring instrument body 2 which has a support portion 22 which supports a laser oscillator 1 so that a laser beam is emitted always in the vertical downward direction, a target portion 23 which is irradiated with the laser beam of the laser oscillator 1, and a pillar portion 21 from which the support portion 22 and the target portion 23 project in directions perpendicular to its longitudinal direction, respectively, and being the same as each other. The inclination of the measuring object is measured, by watching the position of a light spot formed by the laser beam of the laser oscillator 1 at the target portion 23, when a surface of the pillar portion 21 opposite to its surface from which the target portion 23 projects, is abutted against the measuring object, such as a pillar. Since the measurement is hardly affected by the wind as the laser oscillator 1 is used, as compared to a case that a plumb bob is used, the inclination of the measuring object can be measured more accurately.
