An object of the present invention is to provide a component a mounting apparatus capable of accurately determining minute mounting applied pressure. The component mounting head of the component mounting apparatus includes: a movable part having a suction bit section and a movable shaft, a weight compensation mechanism for engaging with the movable shaft to compensate for the gravitational force of the total weight of the movable part and a component suctioned to the suction bit section, on the basis of the total weight; a force determination unit for determining a force applied to the movable part in the vertical direction; and a drive unit for moving the force determination unit in the vertical direction. The control unit of the component mounting apparatus controls the drive unit in such a manner that the determination value of the force determination unit becomes a target value.
