Abstract
A double mirror (Mi) of a light-guiding device of the present invention is made of (i) a first mirror (Mi) that is mounted on a top surface of a base plate (B) and has a reflective surface (S) entering an input beam reflected by the reflective surface (S) and (ii) a second mirror (Mi) that is mounted on a top surface of the first mirror (Mi) and is a prism having a reflective surface (S) reflecting the input beam that has been reflected by the reflective surface (S), the input beam reflected by the reflective surface (S) being totally reflected inside the prism.
