  "abstract": "A component mounter includes a head including multiple holders each holding a nozzle, and includes a fluid pressure circuit connected to the multiple holders, a sensor to detect at least one of a pressure and a flow rate of a fluid flowing through the fluid pressure circuit, and a determination section to set a threshold that increases as an absolute value of a pressure or a flow rate detected by the sensor, and determine that the component picked up by the nozzle is in contact with a board when the absolute value of the pressure detected by the sensor, an absolute value of a change amount of the detected pressure, or an absolute value of the detected flow rate or a change amount of the detected flow rate exceeds the threshold during the mounting operation after the predetermined timing.",
