A construction machine comprising: a plurality of hydraulic pumps ; a first directional control valve that controls a flow of a hydraulic fluid from one of the hydraulic pumps to a first hydraulic actuator ; a pair of first solenoid proportional valves that generate and output pilot pressure for driving the first directional control valve ; a plurality of second directional control valves (24a, 24b; 25a, 25b) that control the flow of the hydraulic fluid from the plurality of hydraulic pumps to a second hydraulic actuator ; a plurality of pairs of second solenoid proportional valves that generate and output pilot pressures for driving the plurality of second directional control valves (24a, 24b; 25a, 25b); at least one electric lever-type operation device that outputs a first operation signal for operating the first hydraulic actuator and that outputs a second operation signal for operating the second hydraulic actuator (5; 6); and a controller that outputs a first command current for driving the first solenoid proportional valve in response to the first operation signal from the operation device , and that outputs a second command current for driving the second solenoid proportional valves in response to the second operation signal from the operation device , characterized in that the controller includes a correction function to correct a command current in such a manner that the command current is higher than a target current corresponding to an operation amount of the operation device for preset predetermined time at a time of starting to operate the operation device from a neutral position of the operation device, and the correction function of the controller corrects the command current such that the controller corrects the first command current and does not correct the second command current or such that a correction value of the first command current is higher than a correction value of the second command current. a plurality of hydraulic pumps ; a first directional control valve that controls a flow of a hydraulic fluid from one of the hydraulic pumps to a first hydraulic actuator ; a pair of first solenoid proportional valves that generate and output pilot pressure for driving the first directional control valve ; a plurality of second directional control valves (24a, 24b; 25a, 25b) that control the flow of the hydraulic fluid from the plurality of hydraulic pumps to a second hydraulic actuator ; a plurality of pairs of second solenoid proportional valves that generate and output pilot pressures for driving the plurality of second directional control valves (24a, 24b; 25a, 25b); at least one electric lever-type operation device that outputs a first operation signal for operating the first hydraulic actuator and that outputs a second operation signal for operating the second hydraulic actuator (5; 6); and a controller that outputs a first command current for driving the first solenoid proportional valve in response to the first operation signal from the operation device , and that outputs a second command current for driving the second solenoid proportional valves in response to the second operation signal from the operation device , characterized in that the controller includes a correction function to correct a command current in such a manner that the command current is higher than a target current corresponding to an operation amount of the operation device for preset predetermined time at a time of starting to operate the operation device from a neutral position of the operation device, and the correction function of the controller corrects the command current such that the controller corrects the first command current and does not correct the second command current or such that a correction value of the first command current is higher than a correction value of the second command current. <EOS>
