Abstract
A number of water spray holes formed on a water spray plate is not less than 130. A diameter of the respective water spray holes is not less than 0.1 mm and not more than 0.5 mm, and an entire aperture area thereof is not more than 30 mm2. With this arrangement, since the entire aperture area of the water spray holes is reduced, it is possible to achieve water-saving effects. Moreover, since the water spray holes are small and provided by a plurality of numbers, the flow of water sprayed from the respective water spray holes is large to feel some strength hitting the skin and to achieve expansion of shower water so that the sense of using the shower may be satisfied. Moreover, since a plurality of small water spray holes is formed, a larger number of minus ion can be generated.
