PROBLEM TO BE SOLVED: To provide a shower head capable of accelerating the generation of micro-bubbles by restraining the bubbles from uniting with each other while simplifying the constitution.SOLUTION: A shower head includes: a head body 2 provided with an introduction channel 30 formed in the interior and a gas-liquid mixing part 11 for sucking the gas to be mixed as bubbles into hot water; a sprinkling plate 3 having a flat plate-like part, which is provided with a plurality of sprinkling holes 31 formed so as to penetrate the plate-like part in the board thickness direction and provided with a swirl current generating passage 32 recessed on the upstream side of the sprinkling holes, for generating a swirl current in hot water. The outlet side of the introduction passage is provided with a passage enlarged part 29 whose sectional area is gradually increased as it goes toward an outlet. A discharge passage is disposed substantially orthogonal to the outlet side part of the introduction passage, and an inlet 36 of the discharge passage has a sectional area in which the volume of hot water flowing into the discharge passage per unit hour is not more than the volume of hot water passing through the introduction passage per unit hour. |
