A vehicular headlamp includes a plurality of excitation light sources; a fluorescent body; a scanning mechanism configured to perform scanning by directing lights emitted from the excitation light sources toward the fluorescent body; and a projection lens through which the lights emitted from the fluorescent body pass such that a light distribution pattern is formed. Irradiation areas of the lights emitted from the excitation light sources and incident on the fluorescent body are different from each other.
