A current sensor and so forth are provided capable of detecting an overcurrent of a wiring line and disconnecting the wiring line while reducing layout space and cost. A current detection part (101u, 102u, 103u) detecting a current flowing through the wiring line, a disconnection mechanism (104u, 105u) disconnecting the wiring line, and a drive circuit driving the disconnection mechanism are included in the same housing (106u). A current detection circuit included in the current detection part and the drive circuit are placed on the same substrate (103u). |
