PROBLEM TO BE SOLVED: To provide a current detection circuit capable of accurately detecting a fine current. SOLUTION: The current detection circuit detects a current value flowing in a coil 1 by detecting a both terminal voltage value of a shunt resistor 2 connected in series with the coil 1. A bypass resistor 6 is connected in parallel with the coil 1, and a product of the maximum current value flowing in the coil 1 and a resistance value of the shunt resistor 2 is 0.5-8.
