PROBLEM TO BE SOLVED: To provide a showerhead capable of generating microbubbles and spraying liquid in large amounts with a simple construction.SOLUTION: A communicating member 20 is disposed in a body portion 15 of a showerhead 10. In the communicating member 20, a plurality of through-holes 24 as pores for microbubbles and a large pore 25 are provided. In the communicating member 20, a plurality of projecting portions 22 are provided, and in each projecting portion 22, a through-hole 24 is formed. When tap water passes through the through-hole 24, as a result of pressure change, gas dissolved in the tap water appears as microbubbles in a mixed state in the tap water. From a first stage to a fourth stage, the amount of the water is sequentially adjusted in accordance with the number of through-holes 24 that have been opened. At a fifth stage, which is for a maximum water amount, the large pore is opened. |
