Abstract: The present invention includes: a nozzle main body (1), which includes a tubular body (8) and a closing flat plate (9) that closes one tube end (8A) of the tubular body (8), and in which an inflow space (?) into which a liquid flows is formed in the tubular body (8); a liquid jetting hole (2) penetrating through the closing flat plate (9) and communicating to the inflow space (?); and a liquid guide (23) arranged in the liquid jetting hole (2) from the inflow space (?). The liquid guide (23) is mounted in the liquid jetting hole (2) from a conical upper surface (23A) so as to form a liquid flow path (?) between the uneven surface of the conical side surface (23C) and a conical inner peripheral surface (2a) of the liquid jetting hole (2).

Abstract: A shower head to jet an air bubble-liquid mixture by mixing air bubbles into the liquid includes a shower nozzle, a flow-adjustment piece, and air introduction passages. The shower nozzle includes an air bubble mixing space. The flow-adjustment piece is arranged in the air bubble mixing space. The air introduction passages cause air to flow into the air bubble mixing space therethrough.
