A water-saving shower using an air pressure, which has a plurality of extended spray tubes, comprising;

• a body having an internal holding space which is capable of containing water internally and an air hole formed at the bottom of the body through which an external air can enter;
• a pressure applying unit positioned at an inner portion of the upper body having an internal cross-sectional area being decreased and then increased toward the bottom of the body comprising an air intake hole connected through the air hole of the body wherein a flow pressure increases by mixing an external air entered through the air intake hole due to a pressure difference of water movement;
• and
• a spray board positioned at the front side of the body having the plurality of extended spray tubes protruding outward by extended externally,
• wherein the air hole comprises a valve allowing the influx of the external air and preventing the reverse flow of the water flowing through an inner tube, the valve comprising i) a cover having a combining hole in the center of the cover and at least one or more air intake holes located on the outer periphery of the combining hole and ii) a carbon wing having a combining teeth, when assembled, being fastened into the combining hole of the cover and extended outward of the combining hole.
