Abstract
Provided is a vehicular headlamp including: an excitation light source; a scanning mechanism configured to scan light emitted by the excitation light source toward a predetermined direction; a projection lens; and a phosphor provided between the scanning mechanism and the projection lens and configured to transmit light scanned by the scanning mechanism toward the projection lens. The phosphor is formed as a curved body that is curved in a direction opposite to a curved image plane of the projection lens.
