Abstract

The refractive index of a third region (430) (base material (200)) is closer to the refractive index of a first region (410) (adhesive layer (310)) than to the refractive index of a second region (420) (gap (320)). Put differently, the absolute value of a refractive index difference between a first medium (510) (adhesive layer (310)) and a third medium (530) (base material (200)) is smaller than the absolute value of a refractive index difference between a second medium (520) (gap (320)) and the third medium (530) (base material (200)). Thus, it is possible to inhibit light advancing from the first region (410) (adhesive layer (310)) side to the third region (430) (base material (200)) side from being reflected on a boundary (552) and to inhibit light advancing from the third region (430) (base material (200)) side to the second region (420) (gap (320)) side from passing through a boundary (554).
