PROBLEM TO BE SOLVED: To efficiently mix a photopolymerizable composition packed in a tank with a gas. SOLUTION: The mixer is equipped with the tank 3 packed with the liquid photopolymerizable composition, a circulation flow channel 6 which has both end parts connected to the tank 3 and circulates the photopolymerizable composition packed in the tank 3, a static mixer 7 arranged in the midstream part of the circulation flow channel 6, a circulation apparatus 17 which circulates the photopolymerizable composition to the circulation flow channel 6 and a nitrogen gas feeder 18 which is arranged at the upper stream of the position of the static mixer 7 of the circulation flow channel 6 and supplies the gas insoluble in the photopolymerizable composition. The static mixer 7 mixes the photopolymerizable composition circulating in the circulation flow channel 6 with the gas supplied from the nitrogen gas feeder 18. COPYRIGHT: (C)2004,JPO
