Abstract
An exposure device includes: a substrate having a first and second surface opposed to each other, wherein a light-emitting element array is mounted on the first surface; a protective sheet covering the second surface while exposing a part of the second surface in the vicinity of an edge of the substrate to define an exposed part of the second surface; a holder that supports a condenser lens array and that supports the substrate, with a gap formed between the holder and the exposed part of the substrate, to position the substrate such that light emitted from the light-emitting element array is condensed on a predetermined irradiation location through the condenser lens array; and a thermally-conductive sealant that covers the exposed part of the second surface of the substrate and seals the gap.
