An apparatus and method of mounting components are provided. The apparatus for mounting components includes: a component supplying unit which supplies the components so that the components move in at least one line; and a plurality of suction nozzles disposed to approach to or retreat from the components, wherein intervals between the plurality of suction nozzles are changeable so that the suction nozzles correspond to positions of the components. The method of mounting components includes: disposing a plurality of suction nozzles corresponding to the positions of the components; picking up the components by using the suction nozzles adjusting intervals between the suction nozzles; moving the suction nozzles to an upper side of a substrate, on which the components are to be mounted; and putting the components down on the substrate.
