A defogging device includes a heating wire configured to heat a windshield. The heating wire includes a plurality of parallel arrangement portions generally parallel to each other and provided such that respective intermediate parts, in the longitudinal direction, of the parallel arrangement portions are placed inside a field angle region. The parallel arrangement portions include two adjacent parallel arrangement portions provided such that respective first ends, in the longitudinal direction, of the two adjacent parallel arrangement portions are connected to each other via a connecting portion outside the field angle region, and respective second ends of the two adjacent parallel arrangement portions are separated from each other without being connected to each other. The second ends of the two adjacent parallel arrangement portions are connected to heat-amount supplement portions provided outside the field angle region and projecting toward their respective counterparts out of the two adjacent parallel arrangement portions.
