An atomizer that mixes gas and liquid and atomizes the mixture,
a gas supply member provided with a gas flow path and a gas supply port for supplying gas;
A liquid supply member provided with a liquid flow path and a liquid supply port for supplying liquid,
The gas supply member has a gas supply surface as a surface forming the gas supply port,
The liquid supply port opens toward an axis perpendicular to the gas supply surface of the gas supply port,
The liquid supply member has a first inclined surface between the liquid supply port and the gas supply port,
The first sloping surface is slanted away from the axis as the distance from the gas supply surface increases in a first cross section including the gas flow path and the liquid flow path; The portion of the liquid supply port that is in contact with the liquid supply port has a shape that approaches the upstream side of the liquid supply port in the flow direction of the liquid as it moves away from the gas supply port when the gas supply port is viewed from above. It has an atomizer. The atomizer according to claim 1, wherein the first inclined surface has a smoothly curved surface shape when viewed from a direction in which the gas supply port is viewed from above. The liquid supply member has a second inclined surface at a position upstream of the first inclined surface in the gas flow direction and facing the flow of gas blown out from the gas supply port,
The atomizer according to claim 1 or 2, wherein the second inclined surface is inclined so as to approach the axis as it moves away from the gas supply surface in the first cross section. The second inclined surface has a shape that approaches the upstream side of the liquid supply port in the flow direction of the liquid as it moves away from the gas supply port when the gas supply port is seen through from a planar direction. 3. The atomizer according to 3. The atomizer according to claim 3 or 4, wherein the first inclined surface and the second inclined surface are connected by a ridgeline. The ridge line has a shape that approaches the upstream side in the flow direction of the liquid in the liquid supply port as it moves away from the gas supply port when the gas supply port is viewed from above. Atomizer. The atomizer according to any one of claims 1 to 6, wherein the liquid supply member further has a liquid supply surface forming the liquid supply port. 8. The atomizer of claim 7, wherein the liquid supply surface extends substantially parallel to the axis of the gas supply port. 9. The opening size of the liquid supply port is such that a maximum dimension in a lateral direction perpendicular to the first cross section is larger than a maximum dimension in a vertical direction intersecting the lateral direction. atomizer. The atomization according to any one of claims 1 to 9, wherein the gas supply port has a maximum dimension in a lateral direction perpendicular to the first cross section, which is larger than a maximum dimension in a vertical direction intersecting the lateral direction. vessel. The atomizer according to any one of claims 1 to 10, further comprising a piezoelectric pump for supplying gas to the gas supply port. The atomizer according to any one of claims 1 to 11, wherein the gas supply member and the liquid supply member are separate bodies.
