A temperature detection function-incorporating current sensor includes a Hall IC, connector terminals for respectively outputting signals, detected by the Hall IC, to the exterior. The Hall IC includes a magnetism detection portion for detecting a magnitude of a magnetic field, a temperature detection portion for detecting an ambient temperature, and a temperature compensation portion for correcting an error of the magnetism detection portion due to temperature dependency based on the temperature detected by the temperature detection portion. The detection signal of the magnetism detection portion, corrected with respect to the error, and the temperature signal detected by the temperature detection portion are outputted via the connector terminals to the exterior. In this current sensor, it is not necessary to provide an additional temperature detection part, and also it is not necessary to effect an operation for connecting such a part to a board. Therefore, the product can be formed into a compact design and a low-cost design, and can be easily assembled.
