Classification: CPC H | IPC H

Claim 0:
1. A plasma generation device comprising:
a plasma head configured to eject plasma gas that is plasmatized;
a gas supply device configured to supply gas serving as the plasma gas to the plasma head;
a pair of electrodes, being provided in the plasma head, which is configured to perform discharging to a part of the gas supplied from the gas supply device so as to generate the plasma gas;
a temperature sensor, being provided in the plasma head, which is configured to measure a temperature of the plasma head;
a control device; and,
a notification device,
wherein the control device executes a cooling process of cooling the plasma head by causing the gas supply device to continue supply of the gas until the temperature sensor measures a temperature equal to or less than a predetermined value after the discharging of the pair of electrodes is stopped, and
wherein the control device executes a notification process of causing the notification device to notify that cooling of the plasma head is abnormal when a predetermined time elapses from stoppage of the discharging of the pair of electrodes during the cooling of the plasma head.
