Zusammenfassung:	PURPOSE: A lighting device is provided to improve an assembly property of a circuit board by reducing a contact resistance between a close protrusion and the circuit board. CONSTITUTION: A circuit board(110) includes a light emitting device(112) on one side thereof and is formed with a panel shape. An insertion unit(122) is formed on a cover(120). The circuit board is inserted into the insertion unit. A close protrusion(130) protrudes from the other side of the insertion unit to closely adhere the circuit board.
