The present invention provides a door mirror for an automobile, in which molding errors are made difficult to occur in a housing and assembling accuracy between the housing and a lamp assy is improved. A housing applied to the door mirror for an automobile is divided into two parts, that is, an upper housing located on the upper side and a lower housing located on the lower side, and a lamp assy constituting a side-turn lamp is disposed between the upper housing and the lower housing. Since the housing is divided vertically into two parts, materials or colors of the upper housing and the lower housing can be made different so that a texture and an appearance of the housing can be easily changed. Moreover, assembling errors between the housing and the lamp assy due to deformation by injection molding or thermal deformation applied during painting can hardly occur, and a gap can be hardly generated between the housing and the lamp assy on the surface side of the housing.
