In an elevator operation panel, a base of a casing includes a back plate portion, a lateral plate portion, and a vertical plate portion. An outer surface of the lateral plate portion, which faces the exterior of the casing, and a vertical direction end surface of the vertical plate portion on the lateral plate portion side are disposed in an identical plane. An L-shaped slit is provided between the back plate portion and the lateral plate portion. The slit includes a rectilinear portion, and a projecting portion that projects into the back plate portion. In a condition where the lateral plate portion is bent relative to the back plate portion, a surface of the lateral plate portion that faces the rectilinear portion overlaps a surface of the back plate portion on an opposite side to a wall.
