Abstract
The present invention has as its object to provide a light source unit in which the relative portion of a detecting device and a condensing device is accurately determined, whereby the detecting device can reliably detect a laser beam, and a scanning optical apparatus using the same, and for this purpose, the present invention provides a scanning optical apparatus having a light source, a holding member for holding the light source, a deflecting device for deflecting light emitted from the light source, a detecting device for detecting the light deflected by the deflecting device, and a condensing lens for condensing the light incident on the detecting device, wherein the holding member positions the detecting device, and holds the condensing lens.
