[0058] based on Figure 1 to Figure 5 , Figure 17 to Figure 20 One embodiment of the present invention will be described as follows. Hereinafter, the LED chip 14 mounted in the light irradiation module 2 (light source: refer to Figure 17 ) as the front surface, and the surface opposite to the surface on which the LED chip 14 is mounted is the back surface.
[0059] In addition, if Figure 17 As shown, in the flexible substrate 15 (substrate), a plurality of LED mounting regions 17 on which the LED chips 14 are mounted are formed in a lattice shape in plan view. Two adjacent LED mounting regions 17 are insulated, and the two LED mounting regions 17 are connected by wiring 16 . In addition, wire bonding connections are also included in the wiring 16 .
[0060] Here, use Figure 18 The positions of the light shielding member 3 and the LED chip 14 in the phototherapy device 1 (photoirradiator) according to the first embodiment of the present invention will be described. S...

[0097] based on Image 6 Other embodiments of the present invention will be described below. In addition, for convenience of description, members having the same functions as those described in the above-described embodiments are given the same reference numerals, and descriptions thereof are omitted. In addition, in this embodiment, the shape of the light shielding member 3a is demonstrated especially about the difference from 1st Embodiment. Image 6 (a)-(e) is a schematic diagram which shows each example of the light shielding member 3a which comprises the phototherapy device 1a which concerns on 2nd Embodiment of this invention. In addition, since the light shielding member 3 of the phototherapy device 1 is replaced with the light shielding member 3a in the phototherapy device 1a, it is not shown in figure.
