In an optical module, an optical element array is an array of optical elements. Further, a lens array is an array of a plurality of lenses. An output point of a light beam of each optical element of the optical element array is caused to coincide with a central line of a corresponding lens of the lens array, and the light beam is made incident on the lens and a parallel beam is output from the lens. When the output point of the light beam of the optical element coincides with an optical axis of the lens, an optical path within the optical element and the optical axis of the lens fail to coincide with each other. |
