[Object] To provide a construction machine that can prevent reduction in work efficiency even in work where a large reaction force is applied to a point of application. [Solution] A hydraulic cylinder drives a working part. A hydraulic circuit supplies hydraulic oil to the hydraulic cylinder. A pressure sensor measures the pressure of the hydraulic oil supplied to the hydraulic cylinder. An input device is operated by an operator. A controller includes a thrust controller that controls the hydraulic cylinder based on the thrust of the hydraulic cylinder. The thrust controller calculates a required thrust value based on an operation amount of the input device, and obtains a thrust measurement of the thrust of the hydraulic cylinder based on the pressure measured by the pressure sensor. The thrust controller controls the hydraulic circuit such that a thrust difference between the required thrust value and the thrust measurement is minimized.
