An optical member comprising:
- a wire containing an electrically conductive substance and being disposed on one surface of the optical member in open-ended arrangement,
- wherein an area in which an optical element is formed on the same surface as the surface on which the wire is disposed,
- wherein the wire is disposed in the area in which the optical element is formed,
- wherein the optical element includes a plurality of sides, and
- wherein two ends of the wire face each other and are disposed adjacent to the same side of the plurality of sides of the optical member, or the two ends of the wire are disposed adjacent to a first side and a second side of the plurality of sides of the optical member, the first side is different from the second side, and the two ends of the wire face the same side of the plurality of the optical member.
