Abstract
Disclosed is a showerhead (1) capable of preventing damages in major or peripheral components and water leakage even if it is increased in size. The showerhead comprises a lower plate (2) formed with a plurality of discharging holes (2c) for discharging shower water therethrough, an upper plate (4) connected to the lower plate and formed with a water inlet port (4c), and a channel-defining member (6) disposed between the lower and upper plates to define an effective channel (6c, 6d) for allowing hot water entered between the lower and upper plates from the water inlet port to be led to each of the discharging holes, and an ineffective channel, so as to reduce a pressure-receiving area of the lower or upper plate to be subjected to a water pressure.
