A communicating member (20) is disposed in a main 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. |
