PROBLEM TO BE SOLVED: To provide a vacuum drying treatment apparatus which improves versatility by making a main body constituting a heating chamber a safe structure improper to a pressure vessel, and which can efficiently perform uniform heating of an object to be treated. SOLUTION: The vacuum drying treatment apparatus is provided with the main body 1 whose lower end side is made a hot water reservoir 1a, a treating chamber 2 which is arranged in the upper section of the hot water reservoir 1a in the main body 1 and inside which the object M to be treated is stored, a vacuum pump 6 which is communicated with the treating chamber 2, a heat exchanger 3 which is arranged in the hot water reservoir 1a, and a boiler 4 where water vapor or hot water is circulated and supplied to the heat exchanger 3. The apparatus is constituted so as to connect the inside of the main body 1 with a depressurizing means, and so as to heat up the surface of the treating chamber 2 with the water vapor of heating medium water in the hot water reservoir 1a generated through heat exchange with the heat exchanger 3.
