PROBLEM TO BE SOLVED: To provide a thermal generator which can acquire a large amount of power generation more efficiently in volume ratio even in case that the temperature conditions of cold and hot heat sources that can be supplied to a thermoelectric element are the same, and a vaporizer mounting that generator. SOLUTION: For the generator, pipelines C and H polygonal in cross section are combined, and a thermoelectric element 11 is arranged closely between adjacent pipelines. This generator increases the amount of power generation efficiently in volume ratio. This generator is applied to a vaporizer, and if it is used for gasification of cryogenic LPG, etc., it can suppress the wasteful energy loss of a hot medium required for gasification, and the latent power generation energy (low-temperature energy) that the cryogenic liquefied natural gas has can be recovered and utilized efficiently.
