Abstract
Provided is a vaporizer that can efficiently cool a carrier gas, improve the effect of preventing a material from being clogged near the outlet port of a gas passage, contribute to prolonging the timing of maintenance and improving operating efficiency, and exert more uniform dispersing effect. A vaporizer includes: a center rod inserted into a carrier gas introduction hole formed in a disperser to form the gas passage in cooperation with the inner wall of the carrier gas introduction hole; a cooling part disposed on the outer circumferential side of the carrier gas introduction hole in the disperser to cool the inside of the gas passage; a cooling member insertion hole formed across almost the entire length of the center rod along the axial direction of the center rod; and a cooling member disposed in the inside of the cooling member insertion hole to cool the center rod.
