Abstract
A production method uses ultrasonic forming but does not leave a bonding face exposed to the exterior in a final product. The production method of a leading edge member of a fan blade comprises the steps of causing superplastic forming by using a combination of a first mold having a flow path for gas and a second mold having a female mold to pressurize a plate member with the gas through the flow path to fit the plate member onto the female mold; bonding a backing with the plate member processed with the superplastic forming; and cutting out a periphery of the plate member to obtain a product shape.
