Abstract
A light irradiation module includes: a substrate; n wiring patterns (n is an integer of 2 or more) on the substrate; and LED elements. Each wiring pattern includes: first to third strip-shaped portions; a first connecting portion connecting the first and second strip-shaped portions; and a second connecting portion connecting the second and third strip-shaped portions. The first strip-shaped portion of an (i+1)-th wiring pattern (i is an integer of 1 to n−1) is disposed between the second and third strip-shaped portions of an i-th wiring pattern. The LED elements are disposed on the second and third strip-shaped portions of each wiring pattern. One electrode of each LED element is connected to the second or third strip-shaped portion immediately thereunder. Other electrodes of the LED elements on the second and third strip-shaped portions of the i-th wiring pattern are connected to the first strip-shaped portion of the (i+1)-th wiring pattern.
