PROBLEM TO BE SOLVED: To provide an optical scanner of laser light, in which a reflecting mirror is certainly made to abut on a positioning part to reduce variations in radiation positions. SOLUTION: The mirror positioning part 13 includes: seat faces 15a, 15b which abut on the reflection face 14 of the reflecting mirror 11; a supporting projection part 17a which abuts on a first face 16 orthogonal to the reflection face 14, wherein a leaf spring 18 pressurizes the back face 21 on the opposite side of the reflection face 14 for making the reflection face 14 abut on the base faces 15a, 15b, and has at least two pressurizing parts which are separated from each other in the transverse direction of the reflecting mirror 11, wherein the pressurizing part which is closer to the supporting projection part 17a in the transverse side direction of the reflecting mirror 11 has pressurizing force larger than that of the pressurizing part which is remote from the supporting projection part 17a.
