Abstract: PURPOSE:To shorten the time for degassing and improve degassing efficiency by controlling the current increase value of current running in a material to be degassed in a vacuum container in the way that the current increase becomes higher in the last half period than the first half period of the degassing time. CONSTITUTION:A material 3 to be degassed is put in a vacuum container 2 and under the control by a controlling apparatus 11 in vacuum, while current being applied gradually to the material 3 to be degassed from a degassing current source apparatus 10, the current is raised. In this case, the current increase value is set to be different in two stages and it is increased in the last half period during which a gas to be removed is a little. That is, since gas emission from the material 3 to be degassed is a little in the last half period. the pressure in the inside of the vacuum container 2 does not become that high. Consequently, even if the current increase value is set to be high, abrupt gas emission from the material 3 to be degassed does not occur and within a short time the pressure reaches the ultimate set vacuum pressure and degassing time can be shortened.
