PROBLEM TO BE SOLVED: To provide a method of manufacturing a wavelength converter whereby the transmissivity can be improved, and to provide the wavelength converter. SOLUTION: The method of manufacturing the wavelength converter 10a comprises the following steps. At first, a crystal is grown. Then a first crystal 11 and a second crystal 12 are formed by sectioning the crystal into two or more so as to mutually reverse polarization. The first and second crystals 11 and 12 are then interlocked in such a way that a polarization inversion structure in which the polarization directions of the first and second crystals 11 and 12 are periodically reversed along an optical waveguide 13 is formed, and the polarization inversion structure satisfies quasi-phase-matching conditions for incoming light 101.
