An optical scanner is disclosed which includes: a first scanning device having a first mirror portion in which a first reflective surface is formed, the first scanning device scanning in a first direction, light which impinges obliquely on the first reflective surface, by oscillatory rotation of the first mirror portion about a first oscillation axi; and a second scanning device having a second mirror portion in which a second reflective surface is formed so as to be generally in parallel to the first reflective surface in a non-active state of the optical scanner, the second scanning device scanning in a second direction intersecting with respect to the first direction, the light exiting the first reflective surface and then entering obliquely the second reflective surface, by oscillatory rotation of the second mirror portion about a second oscillation axis intersecting with respect to the first oscillation axis. The first oscillation axis is oriented substantially parallel to a direction in which the light enters the first reflective surface, when the optical scanner is viewed in a direction perpendicular to the first and second reflective surfaces.
