Abstract
To enable detection of images of peripheral end sections of a first lens face 4 and a second lens face 6, when the positions of the first lens face 4 and the second lens face 6 are measured, to be performed simply by detection operations on the first lens face 4 side, the first lens face 4 is formed having a smaller diameter than the second lens face 6 corresponding to the first lens face 4, and the image of the peripheral end section of the second lens face 6 can be detected from the first lens face side by transmission of light from a light-transmissive substrate 2.
