Abstract: To properly measure the bending amount of an optical waveguide routed in an electronic device or the like. An optical signal outputted with a second wavelength from the optical waveguide is received by a light receiving unit. In this case, the optical waveguide allows propagation only in a basic mode at a first wavelength and the second wavelength is a wavelength where the optical waveguide allows propagation at least in a primary mode in addition to a basic mode. The bending amount of the optical waveguide is obtained by a processing unit on the basis of the amount of a primary mode component included in the optical signal with the second wavelength. For example, the processing unit obtains the bending amount of the optical waveguide by using the ratio of the amount of the primary mode component included in the optical signal with the second wavelength and the amount of the basic mode component included in the optical signal with the second wavelength.
