1. A flux transfer apparatus, comprising:
a stage, having a concave part at a central part of a surface;
a flux pot, having a storage part storing flux, provided with, at a bottom part, a supply part supplying the flux to the concave part, and reciprocally moving on the surface of the stage to supply the flux stored in the flux pot to the concave part through the supply part; and
a detector, detecting a remaining amount of the flux stored in the flux pot,
wherein the stage comprises a light transmission part through which light transmits,
the detector is disposed on a lower side of the light transmission part of the stage, and detects the remaining amount of the flux stored in the flux pot based on a light amount of light emitted into the flux stored in the flux pot through the light transmission part and the supply part and reflected by a liquid surface of the flux,
wherein the detector comprises a light emission part and a light reception part that are both disposed under the lower side of the light transmission part of the stage with respect to the flux pot.
