ABSTRACT:
The present invention relates to an optical element for converting light of prescribed wavelength emitted from a light source into light of wavelength different from the prescribed wavelength for outputting. A first crystal part (20) and a second crystal part (21) having respective surfaces opposed to each other whose coefficients of linear expansion are different by 5 ppm or more are optically polished so that the surfaces opposed to each other include crystallographic axes. An acrylic adhesive whose glass transition point is 75° C. or lower is applied to the adhesive surface of the first crystal part (20) or the second crystal part (21) to stick the first crystal part (20) and the second crystal part (21) to each other. The adhesive is irradiated with light to cure the adhesive and form an adhesive layer (22) having a refractive index of 1.52 or lower. Then, the first crystal part and the second crystal part stuck to each other are cut into a desired size to form the optical element. In the optical element, the separation of the adhesive layer (22) for connecting the first crystal element to the second crystal element and the damage of the crystal parts are suppressed.
