PROBLEM TO BE SOLVED: To make the inductance of a circuit between a power source and a driving circuit section which drives an electric actuator easily reducible in a driving controller for electric actuator which is provided with the driving circuit section and a control circuit section which controls the driving circuit section and in which charging and discharging elements are connected in parallel between the power source and driving circuit section by compactly constituting a circuit for driving and controlling the actuator. SOLUTION: In a driving controller, power supply-side positive electrode terminals 31 and negative electrode terminals 32 which are respectively connected to a positive electrode layer 42 and a negative electrode layer 43 and charging/discharging element-side positive electrode terminals 46 and negative electrode terminals 47 which are respectively connected to the layers 42 and 43 are arranged on substrates which are insulated from each other and constituted in a multilayered structure while carrying the positive electrode layer 42 and negative electrode layer 43 in such a way that the magnetic fluxes generated by the currents flowing from the terminals 31 to the terminals 46 and the currents flowing from the terminals 47 to the terminals 32 compensate each other. |
