1. A specimen pretreatment method for transferring a specimen supported by a first specimen supporting tool to a second specimen supporting tool, the specimen pretreatment method comprising:
transferring a specimen supported by the first specimen supporting tool to a film;
immersing the film and the specimen on the film in a liquid to dissolve the film; and
recovering the specimen from the liquid and supporting the specimen with the second specimen supporting tool, wherein
the first specimen supporting tool comprises a substrate having an opening and a supporting film having a region that overlaps the opening of the substrate for supporting the specimen;
in transferring the specimen to the film, the supporting film and the specimen on the supporting film are brought into contact with the film and the substrate is separated from the supporting film by pushing the substrate such that the specimen is transferred to the film in a state where the supporting film is attached to the specimen and the substrate is removed from the supporting film; and
in supporting the specimen with the second specimen supporting tool, the specimen is supported by the second specimen supporting tool in a state where the supporting film is attached to the specimen.
