PROBLEM TO BE SOLVED: To provide a light emitting device having excellent heat-radiation characteristics.SOLUTION: This light emitting device includes: a support substrate; an organic EL element comprised of a first electrode, an organic EL layer and a second electrode laminated on the support substrate in this order; a first draw-out electrode provided on the support substrate and electrically connected to an external power supply source; a second draw-out electrode provided on the support substrate and electrically connected to the external power supply source; and a connection electrode elongating from the second electrode and connected to the second draw-out electrode. This lighting device also includes a first heat-radiation section elongating from the second electrode on the support substrate. The first draw-out electrode elongates from the first electrode on the support substrate, and the second draw-out electrode is disposed on the support substrate separately from the first electrode and the first draw-out electrode. The first heat-radiation section is electrically insulated from the first electrode and the first draw-out electrode. |
