In a lubricant application system, a prescribed volume of lubricant is transferred from a lubricant discharge port 8 of a prescribed liquid volume discharge device to a rolling element 703 of a rolling bearing 700 in a state in which the lubricant discharge port 8 is positioned directly above and sufficiently close to the rolling element 703 , whereby the lubricant is applied to the interior of the rolling bearing 700 . Further, the application system inspects whether or not a prescribed volume of lubricant is injected from the discharge device for injecting a lubricant into the interior of a rolling bearing 700 . A laser beam L<SUB>1 </SUB>is irradiated between a lubricant discharge port 8 of the lubricant discharge device and the rolling bearing 700 , and a reflected laser beam L<SUB>2 </SUB>reflected by the lubricant when it is discharged from the lubricant discharge port 8 is received by a photoreceptor 116 disposed on the optical axis of the reflected laser beam L<SUB>2</SUB>, whereby whether or not the lubricant is applied to the rolling bearing 700 is determined based on an output from the photoreceptor 116.
