Abstract: An evaporation type burner which can attain light-up and stable combustion of fuel at an early stage by evenly distributing fuel supplied from a fuel supply part to an impregnation member (wick) inside the impregnation member should be provided includes an exudation prevention member having lower fuel permeability than that of the impregnation member in a surface region of the impregnation member opposite to a infiltration region, which is a surface region of the impregnation member where the fuel infiltrates from the fuel supply part into the impregnation member, across the impregnation member. Preferably, a part of the exudation prevention member is embedded inside of the impregnation member, and another part projects from a surface of the impregnation member. More preferably, the exudation prevention member is constituted as a part of the partition member disposed on a downstream side of the impregnation member in a combustion chamber.
