This powder mixed gas generator (20) comprises: a chamber (42) (which includes a container body (23) and a lid (24)) having a space (53) for housing a powder (47) therein; a gas jetting section (25) that is placed in the chamber (42) and jets a gas (54); and a mixed gas discharging section (26) that discharges to the outside a mixed gas (55) in which the gas and the powder (47) are mixed. The gas jetting section (25) jets the gas (54) to form a circulation flow (52) circulating inside the space (53). The mixed gas discharging section (26) includes a mixed gas suction opening (49) for receiving the mixed gas (55). The mixed gas suction opening (49) has an opening facing the flow direction of the circulation flow (52). |
