A scanning image display apparatus (20) includes a light source (11) and a biaxial scanning mirror (12) two-dimensionally scans a scanning surface (23) with the laser beam. When seen from a side perpendicular to an incident plane (15) including a laser beam incident on the biaxial scanning mirror (12) and a laser beam scanned on the scanning surface (23) by the biaxial scanning mirror (12), with the biaxial scanning mirror (12) held at a rotation center position of the reflection surface, the light source (11) and the biaxial scanning mirror (12) are arranged to have a positional relationship where the laser beam is incident on the reflection surface obliquely at an initial angle of incidence α0 either clockwise or counterclockwise with respect to a first normal line of the reflection surface, and the biaxial scanning mirror (12) and the scanning surface (23) are arranged to have a positional relationship where the laser beam is incident on the scanning surface (23) obliquely at an initial angle of incidence &bgr;0 the other of clockwise or counterclockwise with respect to a second normal line of the scanning surface (23).
