Abstract: A light guide pointer and a light emitting pointer device which can reduce luminance unevenness at a light emitting face are provided. A lower face of a main pointer portion includes a separating face extending away from a light emitting face, thus light reflected by a front inclined portion of a light control space, that is not likely to travel in a direction away from the light emitting face, is not likely to reach to a corner which is a boundary between the separating face and a recessed portion. Consequently, light is not likely to be reflected by the corner between the separating face and the recessed portion, thereby preventing luminance to be partially high at the light emitting face and thereby reducing luminance unevenness.
