Abstract: Disclosed is a microcrystalline-to-amorphous gold alloy-plated film having excellent electrical properties and excellent mechanical properties. Physical properties including both the advantageous properties of a crystalline structure and the advantageous properties of an amorphous structure can be obtained by allowing a microcrystalline phase and an amorphous phase to exist in a mixed state at a specific ratio. The average particle diameter of the microcrystals is 30 nm or smaller, the volume fraction of the microcrystals is 10 to 90%, the knoop hardness is Hk 180 or more, the specific resistivity is 200 ??-cm or less. In the film, hardness and abrasion resistance can be improved while maintaining a good specific resistivity value and chemical stability both inherent to gold at practically insignificant levels. Therefore, the film is useful as a material for connecting an electric or electronic component such as a connector and a relay.
