PROBLEM TO BE SOLVED: To obtain a lens curvature measuring apparatus capable of accurately measuring curvature even if the lens to be inspected is a microlens. SOLUTION: For a lens curvature measuring apparatus for measuring the curvature of lens sphere, a lens support member 1 attaching on the circle of lens sphere and positioning a lens 5, a lens support member fixing stage 2 which the lens support member 1 is detachable, a contact probe 3 which is slidable in the lens support member 2 where the tip end contacts the lens sphere, and a displacement measuring means 4 for measuring the moving length of the contact probe 3 are provided. Based on the measured result of the displacement measuring means 4, the curvature of the lens sphere is measured.
