A temperature controller is provided to improve workability and corrosion resistance of the capillary tube by using a steel material instead of a copper. The temperature controller comprises the casing(10), the sensor(20), and the variant part(30) and contacting portion(40). The casing forms the body. The sensing unit passes through one side of casing. The sensing unit has the capillary tube(21). The capillary tube has the working fluid of expansion and contracts according to temperature. The variableness unit is connected to the capillary tube. According to the movement of the variant part, the contacting portion is selectively contacted. The capillary tube has the steel pipe and corrosion resistance plating layer. |
