Light emitted from the end face of an optical fiber 14 goes with an angle of spread. Wavelength-multiplexed light is thrown to the diffraction grating 11 and is demultiplexed by diffracting signal light to angles different by wavelengths. Convex faces 13 are given to a face C in the same manner as a face B in order to converge demultiplexed signal light a having respective wavelengths. Light demultiplexed by the optical wavelength demultiplexing element 10 is converged on optical fibers 15 respectively due to the lens effect of the convex faces 13.
