A component mounting machine (1) which deals with component remaining on a nozzle of a mounting head includes a board conveyance device (2) which conveys a board to a predetermined position, a component supply device (3) which accommodates multiple components therein, a component mounting device (4) on which a mounting head (15) capable of picking up and holding a component by vacuum pumping of a suction nozzle (32) is installed and which mounts a component which is taken out from the component supply device (3) onto a board which is conveyed by the board conveyance device (2), and a control device (5) which controls each of the devices, in which in the component mounting device (4), through drive control of the control device (5), performs a lowering step (S103) of lowering the component, a component release step (S104) of releasing the component with respect to the suction nozzle (32) of the mounting head, and subsequently performs a first lifting step (S105) of lifting the component to a middle height, a component pickup step (S106) which is performed at the height of the first lifting step, and a second lifting step (S107) after the component pickup step.
