Abstract: To measure a film thickness of a coating film (25a) of a flux (25) serving as a bonding paste formed on a transfer stage (24) of a paste transfer unit (7), the film thickness of the coating film (25a) in a transfer area (26) is measured through a light-transmitting member (51) by a light interference method and by an optical type film thickness measuring sensor (53) which is arranged below the transfer stage (24). Thus, it is possible to automatically and accurately measure the film thickness of the flux (25) in the transfer area (26) without requiring any complicated measurement work.
