    摘要： A micro-fluid supplying device having a gas bubble trapping function. The micro-fluid supplying device includes: a fluid supplier including a fluid having a biomaterial; a trap chamber in which a gas bubble is removed from the fluid supplied from the fluid supplier; and a fluid discharger which externally discharges a material supplied from the trap chamber. Material properties of a side wall and a bottom of an inside of the trap chamber are different from each other. The side wall has a better property of wetting with respect to the fluid supplied from the fluid supplier than the bottom.
