A shower head includes a handle and a head portion. The head portion includes shower holes. The handle includes an upstream bubble generator that generates minute bubbles in water. The head portion includes a downstream bubble generator that generates minute bubbles in water in the same manner as the upstream bubble generator. The upstream bubble generator includes a constriction and a tapered portion. The downstream bubble generator has a swirling flow mode. Since minute bubbles are generated on the upstream and downstream sides, the amount of minute bubbles mixed in water becomes larger. This allows for showering by effectively using the function of minute bubbles.
