Viscous fluid supply device

A flux unit includes a flux supply device configured to eject flux to a storage tray, an ejection port configured to eject the flux, and an ejection port moving device configured to move the ejection port in the radial direction of the storage tray. By this, the flux is ejected in a wide range in the radial direction of the storage tray. Also, the storage tray is rotated by a tray rotation device. Thus, the film thickness of the flux ejected in the wide range of the storage tray is adjusted by a squeegee all at once. Thus, the time required for adjusting the film thickness of the flux can be reduced.
