Zusammenfassung:	A structure for measuring a distance on the basis of the principle of triangulation is simplified.A distance measuring module includes a diffractive optical element, an imaging element, and a distance measuring unit. The diffractive optical element emits a predetermined number of line light beams. The imaging element images the line light beams with which the subject is irradiated. The measuring unit measures a distance from the subject by using triangulation on the basis of the imaged line light beams. Thus, by imaging the line light beams emitted via the diffractive optical element, the distance from the subject is measured with a simple structure.
