A fixing apparatus for a light source conductive wire, suitable for use to fix the light source conductive wire. The fixing apparatus has an attaching part, a holding part and a wire protruding part. The attaching part and the holding part are both attached to the light source conductive wire to a backlight module, while the wire protruding part is connected between the attaching part and the holding part to hold the light source conductive wire. The wire protruding part has a wire outlet allowing protrusion of the light source conductive wire. The fixing apparatus prevents the light source conductive wire from being detached during the iron frame assembly of the backlight module, so as to enhance the product yield.
