The heat-treating process of the present invention, the object to be treated kept at a predetermined temperature, of the target, a mist form to claim 1 as a vicinity of a transformation point or higher target temperature than the first transformation point of water tissue started to be transformed in a given tissue a second step of maintaining the predetermined time as the first step of mist cooling by supplying a cooling medium, an object to be treated after the first process, as the stop time of the cooling medium supplied to the mist form, a state an object to be treated after the second step the has a third step of cooling to a temperature not higher than 1 transformation point. According to the present invention, it is possible to provide a heat treatment method that can suppress the non-uniform deformation of the screen and the target tissue water.
