In an electronic component mounting system 10, a mounting management server 60 acquires measurement information relating to a result obtained by measurement of a component P which is stored in a reel 55, registers the acquired measured information in the device information 72 in association with a reel ID, and outputs the measurement information corresponding to the reel 55 to a mounting machine 21 during a mounting process. The mounting process device 20 receives the device information in which the measurement information that relates to the result obtained by measuring the component P stored in the reel 55 and that is associated with the reel ID is registered, when the measurement information is present in the device information of the component to be mounted, the mounting process device 20 executes the mounting process of the component.
