Abstract: An imaging device includes an imaging unit, a lens unit including a plurality of lenses stacked on each other to guide light to the imaging unit, a heater member used for a heater configured to heat a top lens closest to an object among the lenses included in the lens unit, and a reflection suppressor disposed between a region outside of an effective region of the top lens and the heater member, the reflection suppressor being configured to suppress light reflection. The reflection suppressor includes a first reflection suppressor disposed on the top lens side and having an uneven surface, and a second reflection suppressor disposed on the heater member side, the first reflection suppressor being layered on the second reflection suppressor. A surface of the second reflection suppressor facing the heater member is smoother than a surface of the second reflection suppressor facing the first reflection suppressor.
