Provided is a blind spot assist device capable of more easily showing the image of a blind-spot zone continuously with the image directly viewed by a viewer. The blind spot assist device shows the image of the blind-spot zone blocked by an obstacle, and is provided with a pair of parallel plane mirrors to which light representing the image is incident, the pair of parallel plane mirrors comprising a semitransparent plane mirror and a plane mirror opposed to each other. The semitransparent plane mirror is provided on the viewer side for reflecting part of the light and transmitting part of the light. The plane mirror reflects the light to the semitransparent plane mirror. The pair of plane parallel mirrors is provided in such a manner that the width in a direction perpendicular to the travel direction of the light decreases gradually toward the travel direction of the light.
