An electrostatic atomizing apparatus comprising: a liquid nozzle portion made of an insulation material for releasing a liquid column into an open space; a liquid conduit portion (18, 116) made of an insulation material for introducing pressurized liquid into the liquid nozzle portion; a liquid-side electrode for coming into contact with the liquid, the liquid-side electrode being disposed inside the liquid conduit portion (18, 116) or configured to be a portion of the liquid conduit portion (18, 116) and made of a conductive material; a gas conduit portion made of an insulation material and having a gas nozzle portion disposed around the liquid nozzle portion, for converting the liquid column into fine particles to generate an atomized stream which is a stream of gas containing the fine particles, by making a gas stream from the gas nozzle portion act at an atomization point which is a predetermined position of the liquid column released from the liquid nozzle portion into the open space; a liquid pressure attenuating portion provided at a liquid-feeding side of the liquid conduit portion for reducing a pressure of a liquid fed and for converting a flow velocity of the liquid fed into a uniform flow velocity, so that a formation state and a flow velocity of the liquid column that is released into the open space from the liquid nozzle portion are managed by pressure adjustment of the liquid fed; and a ring-shaped induction electrode disposed around the atomization point located in the open space and having an electrode conductor made of a conductive material and coated with an insulation material, wherein the atomized stream of the fine particles electrically charged by applying a predetermined voltage between the liquid-side electrode and the induction electrode from a power supply portion is released; wherein the liquid pressure attenuating portion comprises an orifice portion for restricting a flow rate of the liquid fed and a reflector portion disposed at an outlet side of the orifice portion for reducing a pressure of a liquid flowing out of the orifice portion and converting the flow velocity of the flowing liquid into the uniform flow velocity. a liquid nozzle portion made of an insulation material for releasing a liquid column into an open space; a liquid conduit portion (18, 116) made of an insulation material for introducing pressurized liquid into the liquid nozzle portion; a liquid-side electrode for coming into contact with the liquid, the liquid-side electrode being disposed inside the liquid conduit portion (18, 116) or configured to be a portion of the liquid conduit portion (18, 116) and made of a conductive material; a gas conduit portion made of an insulation material and having a gas nozzle portion disposed around the liquid nozzle portion, for converting the liquid column into fine particles to generate an atomized stream which is a stream of gas containing the fine particles, by making a gas stream from the gas nozzle portion act at an atomization point which is a predetermined position of the liquid column released from the liquid nozzle portion into the open space; a liquid pressure attenuating portion provided at a liquid-feeding side of the liquid conduit portion for reducing a pressure of a liquid fed and for converting a flow velocity of the liquid fed into a uniform flow velocity, so that a formation state and a flow velocity of the liquid column that is released into the open space from the liquid nozzle portion are managed by pressure adjustment of the liquid fed; and a ring-shaped induction electrode disposed around the atomization point located in the open space and having an electrode conductor made of a conductive material and coated with an insulation material, wherein the atomized stream of the fine particles electrically charged by applying a predetermined voltage between the liquid-side electrode and the induction electrode from a power supply portion is released; wherein the liquid pressure attenuating portion comprises an orifice portion for restricting a flow rate of the liquid fed and a reflector portion disposed at an outlet side of the orifice portion for reducing a pressure of a liquid flowing out of the orifice portion and converting the flow velocity of the flowing liquid into the uniform flow velocity.
