Abstract: An LED light source device capable of making the amount of light of an emitting region a predetermined amount of light or more and uniformizing the amount of light is provided. The LED light source device 1 includes an ultraviolet LED array 3 including an LED juxtaposition region R in which LEDs 10 that emit ultraviolet light toward the front are juxtaposed, and a light transmitting member 4 provided on the front side of the LED juxtaposition region R of the ultraviolet LED array 3 so as to be opposed thereto, showing a rectangular parallelepiped outer shape, and formed of a material containing quartz. At a front surface 10a of the LED 10, an emitting surface S surrounded by a marginal portion 11 of a predetermined width H and for emitting the ultraviolet light is provided. Here, when viewed from the front, an end of the light transmitting member 4 is located between inside by 1/2 of the predetermined width H and outside by 1/2 of the predetermined width H with respect to an end of the LED juxtaposition region R of the ultraviolet LED array 3.
