PROBLEM TO BE SOLVED: To provide a lighting device capable of decreasing the volume of a sealing portion and improving the take-out efficiency of light.SOLUTION: A lighting device is equipped with a body portion; a substrate provided on the body portion; a wiring pattern which is provided on a surface of the substrate and has a plurality of wiring pads; a plurality of light emitting elements which is provided on the wiring pattern, and has electrodes near a peripheral edge on the opposite side to a side provided on the wiring pattern; a plurality of wiring respectively connecting the plurality of wiring pads and the plurality of electrodes; and a sealing portion which covers the plurality of light emitting elements. The plurality of light emitting elements is at least partially connected in series, and includes a plurality of first light emitting elements and a plurality of second light emitting elements having different electrode positions from the first light emitting elements. The plurality of light emitting elements is oppositely disposed across a first position. The electrodes of the plurality of light emitting elements are provided at positions rotationally symmetric about the first position, and the electrodes of the plurality of light emitting elements are provided at positions rotationally symmetric about the first position.SELECTED DRAWING: Figure 11 |
