PROBLEM TO BE SOLVED: To provide an inexpensive current detection circuit capable of outputting a voltage value accurately indicating current values flowing in two current paths, a current detection device comprising the current detection circuit, and a switching device.SOLUTION: As a current path flowing in a conductor 18, there are a first current path in which a current flows from a first conductive part 21 to a second conductive part 22 and a second current path in which a current flows from a third conductive part 23 to the second conductive part 22. The first conductive part 21, the second conductive part 22 and the third conductive part are formed into a tabular shape, a point P1 is positioned on a plate surface of the first conductive part 21 and a point P2 is positioned on a plate surface of the second conductive part 22. A current detection circuit 15 detects a value relating to a potential difference between the points P1 and P2 and outputs a voltage value corresponding to current values flowing in the first current path and the second current path.SELECTED DRAWING: Figure 2
