A construction machine includes a vehicle body having, a moving section, a driving mechanism, a manipulation device that receives a manipulation, a controlling unit, a manipulation detecting unit that detects the manipulation given to the manipulation device, and an obstacle detecting device that detects an obstacle in a periphery of the vehicle body. The controlling unit executes emergency-stop-processing and continuous-stop-processing. The emergency-stop-processing is executed to stop the operation of the moving section regardless of a signal from the manipulation detecting unit upon detection of the obstacle by the obstacle detecting device when the controlling unit controls the driving mechanism to drive the moving section. The continuous-stop-processing is executed to keep the operation of the moving section stopped when the obstacle detecting device does not detect the obstacle and the manipulation detecting unit detects manipulation when the operation of the moving section is stopped by the emergency-stop-processing.
