Abstract: A projector device of the present disclosure includes a luminous tube made of quartz glass, a concave reflecting mirror in which the luminous tube is disposed, and an optical unit for projecting an image by utilizing light emitted from the concave reflecting mirror. The luminous tube has a luminous part, in which at least mercury is enclosed inside and a pair of electrodes is disposed so as to face each other, and a pair of sealing parts extending from the luminous part in opposite directions to each other. The luminous tube is disposed so as to direct the pair of electrodes in a vertical direction. A region of the image projected from the optical unit is a horizontally long rectangle.
