<P>PROBLEM TO BE SOLVED: To obtain a device for measuring a posture which can measure highly accurately both of an angle of rotation around the measuring optical axis of a subject and an angle of inclination to the measuring optical axis and is small-sized and lightweight. Ž<P>SOLUTION: A reflecting element 40 includes a first reflecting plane 41 so provided as to be perpendicular to the optical axis L and a pair of second reflecting planes 42 and 43 so provided as to intersect each other perpendicularly, and is so constituted that first light is reflected from the first reflecting plane 41 and second light from the paired second reflecting planes 42 and 43. Based on the amount of change in the position of a reticle image formed by the first light reflected from the first reflecting plane 41, the angle of inclination of a camera 2 to the optical axis L is measured, and based on the amount of change in the angle of rotation of the reticle image formed by the second light reflected from the paired second reflecting planes 42 and 43, the angle of rotation of the camera 2 around the optical axis L is measured.
