A component mounting head for mounting a component includes a head main body; a nozzle holding tool held on the head main body capable of lifting and lowering; a suction nozzle fitted into a lower end portion of the nozzle holding tool and movable in an up-down direction, and picks up and holds the component on the lower end portion of the suction nozzle, a first lifting and lowering device lifting and lowering the nozzle holding tool, a second lifting and lowering device lifting and lowering the suction nozzle, an acting force detector detecting an acting force acting on the suction nozzle in the up-down direction, and a control device controlling the second lifting and lowering device based on the acting force detected by the acting force detector, when the component is mounted, in which a bearing is interposed between the suction nozzle and the nozzle holding tool.
