Abstract: A current sensing module for measuring a current includes a conductive substrate, a frame, a circuit board and a magnetic sensor. The conductive substrate has two terminals and at least one slot. The frame has two side portions and a bottom portion, wherein the bottom portion connects the two side portions to form an opening ring-shape. At least one of the two side portions is disposed in the at least one slot, such that the two side portions surround a partial path of the current. A gap exists between two top ends of the two side portions. The circuit board is disposed with respect to the conductive substrate. The magnetic sensor is connected to the circuit board and located in a space between the two side portions rather than in the gap. The magnetic sensor senses the current and generates a first current sensing signal correspondingly.
