PROBLEM TO BE SOLVED: To provide a wide angle rear-view mirror with no dead angle and very small distortion of an image (rear visibility) reflecting in the mirror. SOLUTION: This wide angle rear-view mirror has a mirror member 1 composed of a main mirror surface part 10 installed on the inside, a first wide angle part 20 installed in the outside upper part, and a second wide angle part 30 installed in the outside lower part, the main mirror surface part 10 is extended to the upper and lower ends of the mirror member 1 in the same curvature on the basis of the center line 40 in the lateral direction installed in the mirror member 1, the main mirror surface part 10 is connected to the first wide angle part 20 through a first boundary 11 formed so as to bend from the upper end of the mirror member 1 to the outer end, connected to a second wide angle part 30 through a secondary boundary 12 formed so as to bend from the lower end of the mirror member 1 to the outer end, and the curvatures of the first wide angle part 20 and the second wide angle part 30 are different from that of the main mirror surface part 10, and gradually increased.
