PROBLEM TO BE SOLVED: To provide a liquid jet apparatus capable of determining in a lump whether or not a plurality of ultraviolet sources are normal. SOLUTION: The liquid jet apparatus includes: a recording head 25 for producing a jet of an ultraviolet curable ink onto continuous paper 12 so that an image corresponding to liquid jet data is formed on the continuous paper 12; an ultraviolet irradiation apparatus 27 in which a plurality of ultraviolet LEDs 28, for irradiating the ink deposited on the continuous paper 12 with ultraviolet by jet from the recording head 25, are arrayed along a direction that intersects the relative movement direction to the continuous paper 12; a camera 29 for acquiring the image, formed on the continuous paper 12 based on the ultraviolet irradiation from the ultraviolet irradiation apparatus, as image data along the arraying direction of the ultraviolet LEDs 28; and a control apparatus for comparing the image data acquired by the camera 29 with the liquid jet data, and determining whether or not the plurality of ultraviolet LEDs 28 are normal based on the comparison results.
