To provide a nail care device capable of emitting UV light in a high light utilization efficiency than in conventional devices.

The nail care device (100) includes a covering part (1), a light-emitting component (2), and a light-emitting control module (9). The covering part (1) is configured for covering a tip of a digit of a limb. The light-emitting component (2) is disposed in the covering part (1) in a manner that light emitted by the light-emitting component (2) irradiates a nail on the tip of the digit covered by the covering part (1). The light-emitting control module (9) is coupled to the light-emitting component (2) and is operable to control operation of the light-emitting component (2).
