PROBLEM TO BE SOLVED: To solve such a problem that a conventional door mirror for a passenger car, or an automobile similar to the passenger car has a dead angle where the driver cannot see, such as a rear wheel tire of the automobile and just beside the driver. SOLUTION: A fisheye lens, a compound eye lens, and a prism which is a principle of a Fresnel lens provided on a surface of a conventional door mirror forming an extremely slight convex lens or concave lens, are formed in an inner part of one of the conventional door mirrors, at the upper and lower parts, both of the right and left ends, or the center part. When a driver looks at one of the door mirrors, the driver can see an upper and lower views in a vehicle traveling direction, an upper and lower views at 180 degree of the right and left, just beside the driver, and a rear view without moving a view line from the inner part of the door mirror, thus generating no dead angle.
