description A charged particle beam apparatus includes: a specimen chamber; a specimen holder that is disposed in the specimen chamber; a specimen exchange chamber that is connected to the specimen chamber; a transporting mechanism that transports a specimen between the specimen chamber and the specimen exchange chamber; a first temperature sensor that measures a temperature of the specimen holder; a second temperature sensor that measures a temperature of the transporting mechanism; and a control unit. The control unit: calculates a temperature difference between the specimen holder and the transporting mechanism based on the temperature of the specimen holder and the temperature of the transporting mechanism when the control unit has received an instruction to transport a specimen; determining whether the temperature difference is a threshold or more; and stopping transportation of a specimen when the control unit has determined that the temperature difference is the threshold or more.
