Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a lighting apparatus using a light emitting device, and to provide a lighting apparatus using a light emitting device easy to connect, adaptable to difference in numbers of connecting light emitting devices and color differences, while minimizing deterioration of luminance. SOLUTION: On the surface of a printed board, a conductor pattern is formed for supplying power, and a plurality of light emitting devices 3 are arrayed and mounted. On the back surface, electronic parts of a lighting circuit 9 that lights the light emitting device 3 are mounted. The printed board having these devices is housed and fixed in a structure having a surface of light emission material, opposing to the light emitting device 3, to form a lighting apparatus. A lighting circuit 9 is formed by connecting a circuit connecting multiple of light emitting devices 3 in series in a constant current circuit having a transistor 11, a Zener diode 12 and resistors 13, 14, and connecting an impedance device 17 between the circuit and a power having 10 rectifying circuits and 15 smoothing circuits.
