The current measurement device (1, 2) includes a first sensor (SE1) configured to detect a direct current magnetic field and a low-frequency alternating current magnetic field generated due to the current (1) flowing through the conductor (MC) to be measured, a second sensor (SE2) configured to detect alternating current magnetic fields from a low frequency to a high frequency generated due to the current (I) flowing through the conductor to be measured, a first calculator (21, 21A) configured to calculate the current flowing through the conductor to be measured from a detection result of the first sensor using distance information indicating a distance (r) between the first sensor (SE1) and the conductor (MC) to be measured, a second calculator (22) configured to calculate the current flowing through the conductor to be measured from a detection result of the second sensor, and a synthesizer (23) configured to synthesize a calculation result of the first calculator with a calculation result of the second calculator.
