In a mounting system including multiple mounting machines, there is provided a mounting system that is capable of reducing the number of measurement devices that measure electrical characteristics of an electronic component. A control device controls a switching device in order to connect a measurement device and a mounting machine that transmitted request information for measuring the electrical characteristics of the electronic component. When transmitting an instruction for starting measurement to the measurement device and receiving a characteristic measurement value from the measurement device, the control device transfers the received characteristic measurement value to the mounting machine that transmitted request information.
