Zusammenfassung:PURPOSE:To provide the method for measuring the inclination of the optical axis of an optical lens which correctly makes X-Y adjustment and skew adjustment in a short period of time by previously measuring the inclination of the optical axis of the optical lens and roughly adjusting the inclination of the optical axis according to this measured inclination. CONSTITUTION:This instrument 10 for measuring the inclination of the optical axis is so constituted as to have a plate 13 which is supported at one point and is pressed to the end face of a lens part including a frame which supports the optical lens and has the end face nearly perpendicular to the optical axis of the optical lens and a sensor 14 which detects the inclination direction and angle of this plate.
