Humidifier and air-conditioning apparatus including humidifier

A humidifier comprising:

• an electrode being conductive;
• water absorbing humidification bodies positioned to sandwich the electrode and having respective surfaces opposing each other with the electrode between the respective surfaces;
• a power supply to apply a voltage to the electrode;
• a water supply unit to supply humidification water to the water absorbing humidification bodies;
• and
• a blower to cause air to flow in a space between the water absorbing humidification bodies sandwiching the electrode,
• wherein the electrode provided with the voltage by the power supply includes protruding portions extending perpendicularly from opposite sides of the electrode each in a first direction toward the water absorbing humidification bodies and having a shape of one of a triangular shape, a needle shape, or a sawtooth shape and that are configured to generate ion wind flowing in a different direction to the flow of air,
• wherein the blower is positioned to blow the air to flow in a second direction perpendicular to the first direction that the protruding portions extend.
