A liquid in which fine solid Sn particles are dispersed in a resin is
accommodated inside the heated tank 4. The resin pressurized by a
pressurizing pump is conducted to a nozzle 1, so that a liquid-form resin
is caused to jet from the tip end of the nozzle 1 that is disposed inside
a vacuum chamber 7. The liquid-form resin which is caused to jet from the
nozzle 1 assumes a spherical shape as a result of surface tension, and is
solidified by being cooled in a vacuum, so that a solid-form target 2 is
formed. A laser introduction window 10 used for the introduction of laser
light is formed in the vacuum chamber 7, and laser light generated from a
laser light source 8 disposed on the outside of the vacuum chamber 7 is
focused by a lens 9 and conducted into the vacuum chamber 7, so that the
target is converted into a plasma, thus generating EUV light.
