PROBLEM TO BE SOLVED: To stably deliver the sufficient vaporized fuel corresponding to the case of the high flow rate of fuel or cryogenic temperature by avoiding the trouble of a heater unit, obtaining the high heated vaporization capacity and the rapid rising in temperature as to an LPG heating device. SOLUTION: The LPG heating device is arranged in an LPG supply device to heat/vaporize and deliver the liquid LPG. A plurality of heater units 33A are arranged in parallel in a heat exchanging chamber 34A at predetermined intervals to form clearance to form an LPG passage 38a which heats the passing liquid LPG. In the heater unit 33A, a plus electrode 336 is arranged in the center, a support case 330 is provided at both the sides to support PTC heaters 320, 320, minus electrodes or heating plates 337, 338 are arranged in contact with covering all the outer peripheral surface but for a plus electrode pick-up part to form a casing, and rubber seals 336a, 336a are arranged so as to make the casing inside be in a pneumatic/liquid-tight state.
