Abstract

PROBLEM TO BE SOLVED: To provide a shower head including a configuration capable of adjusting a dissolution rate of a bathing agent to be stored.SOLUTION: In a hot-water mixing region S3, hot water (F2) containing a bathing agent component is stirred with hot water (F1) directly flowed in from a flow path 101a and become hot water (F3) mixed with the bathing agent. Hot water flowing into a first flowing region S1 where the bathing agent 130 is stored does not make a whole amount of hot water passing through a flow path 101a flow in but makes a part of it flow in. Further, since the amount of the hot water flowing into the first flowing region S1 can be adjusted by an inflow amount adjusting mechanism that uses an outer opening 117 and an inner opening 123, the dissolution rate of the bathing agent 130 can be adjusted.
