PROBLEM TO BE SOLVED: To suppress the occurrence of chocking due to production of tar of a vaporization accelerator and to perform excellent combustion by preventing the occurrence of poor vaporization. SOLUTION: A vaporization element 30 having a shape of a cylindrical brush formed by putting a number of flocked wires 29 between a plurality of core wires and twisting the core wires 28 28 is disposed in a vaporization chamber 26 disposed in a vaporizer 21 for vaporizing fuel. A reticulate vaporizing netting 32 is disposed at the whole or a part of the inner wall of the vaporization chamber 26 in a manner to cover the bottom of a joint part between the vaporizer 21 and a cap 27 in a state to adhere to the inner wall of the vaporization chamber 26. A different reticulate pulse preventing netting 33 is fixed at the end part on the nozzle 23 side of a vaporization netting 32 by spot welding to form multiple structure.
