Provided is a safety confirmation mirror whereby a blind spot near a corner of a passageway can be easily seen more clearly. The safety confirmation mirror includes, as a reflective surface (2), a portion of a Fresnel mirror (3) offset to one side of the widthwise center (C1). Accordingly, when the safety confirmation mirror is installed on a wall surface of a passageway at a T-shaped, L-shaped, or cross intersection, the reflective surface 2 reflects the blind spot of a passageway in one direction that a person is going to turn, and the person can see the conditions thereof. Moreover, the reflective surface 2 does not reflect the conditions in the unnecessary direction. Accordingly, the person looking at the safety confirmation mirror (1) is not confused by the unnecessary image and can easily see the blind spot near the corner of the passageway more clearly. |
