<P>PROBLEM TO BE SOLVED: To provide a current measuring device having a small noise generated in a current supplied to an electronic device, and for measuring highly accurately the current supplied to the electronic device. Ž<P>SOLUTION: The current measurement device of an electronic device for measuring the current receiving from its input terminal includes: a first capacitor for storing standard supplying voltage to be a standard voltage for supplying to the electronic device while measuring the current; a first switch for storing the standard supplying voltage to the first capacitor by connecting the electric source before the current measurement time, and cut the electric source from the first capacitor while measuring the current; a current supplying part for supplying the standard supplying voltage stored in the first capacitor and current to the electronic device based on the terminal voltage of input terminal while measuring the current; and the first current measurement part for measuring the supply current supplied to the electronic device.
