At least some of the LED chips are disposed on the support surface and form a first main surface where light emitted from with a part of the support surface without the LED chips. Each of the LED chips includes a first electrode and a second electrode. Light emitted from at least one of the LED chips passes through the transparent substrate and emerges from the second main surface. An illumination device includes the light emitting element and a supporting base.
