PROBLEM TO BE SOLVED: To provide a linear solenoid valve control device capable of reducing oil shock noises, and saving power consumption. SOLUTION: This linear solenoid valve control device 100 comprises a flow path, in which a fluid flows, a linear solenoid 1a, a valve 1 for opening and closing the flow path, and a valve control part 2 for controlling an opening degree of the valve 1 according to a predetermined valve control quantity by applying an exciting current to the linear solenoid 1a. The device comprises a bite detection part 28 for detecting that foreign matters in the fluid bitten between the flow path and the valve 1, and a size estimation part 29 for estimating the size of the bitten foreign matters when the bite of the foreign matters is detected by the bite detection part 28. The valve control part 2 applies the exciting current for controlling the valve 1 to the opening degree corresponding to the size of the foreign matters estimated by the size estimation part 29 to the linear solenoid 1a.
