PROBLEM TO BE SOLVED: To provide an angle measuring instrument for measuring inclination angles in respective measurement operations at high speed, an angle adjuster, and an optical measuring instrument. SOLUTION: At step S5, a light projection element 15 is caused to perform light projection operation while giving a drive signal to a two-dimensional CCD 18. At step S6, domain information is obtained from a domain information storage part 20 to read out a first gravity center position P1 from a gravity center position storage part 21. In step S7, a pixel specific domain E1 is specified whose reference point is the center position P1 on an imaging surface 18A. Since the spot position of reflected light L2 on the imaging surface 18A is illuminated in the specific domain E1, received light signals from pixels positioned in the specific domain E1 are sorted out from imaging signals and a gravity center position P2 can be calculated by applying to them a calculation expression for the center position. An inclination angle of a support arm piece W1 is measured and found to beθ2 based on a positional difference between the center position P2 and an original point O (step S9).
