PROBLEM TO BE SOLVED: To provide a vaporizer free from clogging of a nozzle with tar by preventing a high-boiling component in vapor from flowing into the nozzle.SOLUTION: A vaporizer is adapted to arrange a holding member 144 in a vaporizing container 14 with a vaporization filter 143 to collect a high-boiling component stored inside the holding member 144 so that a vapor flow passage is formed by the holding member 144. Vapor generated in the vaporizing container 14 flows along the vapor flow passage from a space section 146 to a vapor flow intake 23 through the vaporization filter 143 and is injected through a nozzle section 20. Because the high-boiling component is filtered out while the vapor flows through the space section 146 and the vaporization filter 143, the vaporizer prevents the high-boiling component from flowing into the nozzle 20. In addition, the vaporizer can be simply configured because formulation of the vapor flow passage and holding of the vaporization filter 143 are achieved by one component.SELECTED DRAWING: Figure 3 |
