摘要:
Provided are a movable contact, a variable resistor, and a method for manufacturing a movable contact that can suppress a cost increase. The movable contacts are spaced apart from each other. The variable resistor, having a resistor, an electrode and the movable contact, comprises: a first wire rod group which has a plurality of first wire rods made of a precious metal and in which the plurality of first wire rods are arranged along the resistor; a second wire rod group which has a plurality of second wire rods made of a metal other than the precious metal and in which the plurality of second wire rods are arranged along the electrode; and a shaft-shaped member which is disposed to cross the first wire rod group and the second wire rod group and is welded to the first wire rod group and the second wire rod group.
