To provide an active water generator which can efficiently activate water.

The active water generator includes an introduction pipe for capturing water from city water to introduce the water into the bottom part of a vessel body of the active water generator, a spiral blade for making the water introduced into the vessel body into swirl flow, ceramics for activating the water rising from the bottom part and a delivery pipe for removing the activated water outside. Further, the spiral blade is longitudinally provided inside the vessel body, and the ceramics are provided so as to rise along a blade of the spiral blade. Thereby, the water is made into the swirl flow by the spiral blade, the water in a swirl state is brought into contact with the ceramics, and the efficiency on water activation is enhanced.
