The present invention provides a backlight module and a light source device used therein. The present invention also provides the light source device manufacturing method. The light source device comprises a circuit substrate, light-emitting elements and a solder-resist reflective layer. The circuit substrate has a metal circuit layer and contacts thereon. The light-emitting elements are arranged in the form of arrays on the circuit substrate and are connected to the contacts. One end of each contact is connected to the metal circuit layer, and the other end is connected to the light-emitting element. The solder-resist reflective layer is formed on the circuit substrate and is disposed on the same side as the light-emitting elements. The solder-resist reflective layer covers the metal circuit layer but exposes the contacts.
