Compact design is achieved to minimize blocking of the field of view of a stereomicroscope apparatus. Furthermore, astigmatism is decreased to produce a high-quality image. An optical-scanning microscope apparatus includes a light source, a light-transmitting member for transmitting light from the light source, an apparatus main body for illuminating a subject with the light transmitted by the light-transmitting member, and a photodetector for detecting return light returning from the subject via the apparatus main body and the light-transmitting member. The apparatus main body includes a collimating optical system for converting the light transmitted by the light-transmitting member into collimated light, a scanning mirror for deflecting the collimated light emitted from the collimating optical system at a deflection angle smaller than 90° to scan the light over the subject, a focusing optical system for focusing the light scanned by the scanning mirror onto the subject, and a pupil-projection optical system disposed between the focusing optical system and the above-described scanning mirror.
