Abstract
A current sensor sending an output to the outside through a connector does not affect the precision of the sensor even when an external connector is inserted or removed. The current sensor has a bus bar and a case housing part of the bus bar. The case has an open upper surface and a lid covering the upper surface. A circuit board is fixed to the case body with three caulking portions. The circuit board includes a fixed area enclosed by these caulking portions and an extended portion extending from two of these caulking portions. The lid is provided with two lid-side stoppers. Inside the case body, case-body-side stoppers are provided at three positions. When an external connector is connected to or removed from the connector, the warp of the extended portion is suppressed by the case-body-side stoppers and lid-side stoppers.
