<p>An ultraviolet irradiator including a housing having an ultraviolet irradiation port through which the target is irradiated with the ultraviolet light, an ultraviolet lamp that emits ultraviolet light, a water-cooling jacket in which the ultraviolet lamp is mounted, a reflection plate that reflects light emitted from the ultraviolet lamp, the ultraviolet lamp, the water-cooling jacket and the reflection plate being mounted in the housing, and ultraviolet light emitted directly from the ultraviolet lamp and reflection light reflected from the reflection plate being irradiated to the outside of the housing, a heat withdrawing mechanism that withdraws heat of the reflection plate and discharges the heat to the outside of the housing; and a heat transfer member that transfers ambient heat in the housing to the heat withdrawing mechanism so that the heat withdrawing mechanism withdraws the ambient heat.</p> |
