Abstract: A current sensor includes busbars through which a current to be measured flows, magnetic detectors capable of detecting a magnetic field generated when the current to be measured flows through the busbars, a storage space storing the magnetic detectors, and a housing with which part of the busbars is integrated. Ends of the busbars are connected to an external first unit including a cooling device, and other ends of the busbars are connected to an external second unit whose temperature becomes higher than that of the first unit when the current to be measured flows. In the current sensor, which is capable of measuring a current value of the current to be measured from a result of the detection performed by the magnetic detectors, the housing has first vents penetrating from the inside of the storage space to the outside on a side facing the first unit.
