Abstract: A mirror, when attached along a curved surface, facilitates recognition of an image in a blind spot by reducing a feeling of strangeness caused by the aspect ratio of the image. Many linearly-extending strip reflective surfaces 5a are arranged on a surface of a sheet 2 to be parallel and adjacent to one another. An inclination angle A formed between a width direction of each of the strip reflective surfaces 5a and a surface direction of the sheet 2 is sequentially changed with an increase in a distance in a direction transverse to an extension direction of the strip reflective surfaces 5a. An aggregate of the strip reflective surfaces 5a has a cylindrical convex mirror function, and the mirror 1 is bendable in a cylindrical shape about an axis parallel to the direction transverse to the extension direction of the strip reflective surfaces 5a.
