To provide a spraying apparatus of a humidifier which is structured so that fine sprayed particles are evenly discharged even without a long spraying port.

In this spraying apparatus of the humidifier for humidifying by spraying water and supplying it to an indoor side, a filter in a fan shape for spirally ascending the sprayed particles is provided on a discharge flow passage. As relatively large sprayed particles are filtered from the sprayed particles and smaller sprayed particles spirally ascend and flow to a wider flow passage, flow rate of the sprayed particles increases and comfortable humidification is realized in wider area. The spraying apparatus of the humidifier is provided which can prevent malfunction of the humidifier itself and peripheral articles caused by water drops.
