Disclosed are an illumination device and an inspection device of a tire that can easily detect abnormality of the shape of the manufactured tire. A photographing portionphotographs a inner peripheral surface of a tire T, while a driving portionrelatively rotates the tire T and a inspection portionaround an axis of the tire T, in the state of irradiating a light from a light source unitdisposed along the inner peripheral surface of the tire T toward the circumferential direction of the tire T.

Provided is a method of continuously producing a phosphorus-containing copper alloy wire by adding phosphorus or an element which is less soluble than phosphorus to molten copper. The method includes: adding an element less soluble into a heating furnace for maintaining molten copper sent from a melting furnace at a predetermined high temperature; transferring the molten copper sent from the heating furnace to a tundish; adding phosphorus to the molten copper after decreasing the temperature of the molten copper in the tundish; supplying the molten copper from the tundish to a belt wheel-type continuous casting apparatus; and rolling a cast copper material output from the belt wheel-type continuous casting apparatus, thereby continuously producing a phosphorus-containing copper alloy wire.
