To prevent a liquid material outlet from being clogged with accretion. Disclosed is a vaporizer, which vaporizes a liquid material, discharged from the outlet of a nozzle, in a heated vaporization chamber to produce a raw gas, and which is provided with a cylindrical heated member, which is disposed between the front end of the nozzle and the vaporization chamber so as to cover the perimeter of the outlet, a carrier gas ejection port, which ejects a carrier gas from the vicinity of the outlet, a mixing chamber, wherein the liquid material discharged from the outlet is mixed with the carrier gas, which ejects the mixture toward the vaporization chamber, a first heating part, which heats the vaporization chamber from its exterior, and a second heating part, which heats the heated member from its exterior. |
