Abstract: A humidifier capable of sending forth fragrance includes a housing, a water-detecting device, an electric heating member, a top covering and a perfume holding member. A water-containing hollow is provided within the housing. The detecting device and the heating member are arranged such that water held in the hollow can flow to both. The top covering is coupled to the housing, and has a steam-ejecting hole. The perfume holding member is coupled to, and covers a part of the ejecting hole. When the detecting device detects presence of water, the heating member will heat the water into steam, which is then ejected from the ejecting hole, and heats the perfume for it to be sent forth to the air.
