An imaging device includes an imager including an optical receiver, an optical element located on an optical path extending to the optical receiver, a substrate to which the imager is fixed, a casing which covers the imager and the optical element, and a dustproof light-shielding member interposed between the imager and the optical element. The dustproof light-shielding member has an opening which allows light to pass, and a fitting portion formed like a recess in which the imager is to be fitted. The dustproof light-shielding member is held between the imager and the optical element to form a sealed space, protecting a space between the imager and the optical element against dust.
