An ultrasonic mist inhaler, comprising:

• a mouthpiece for inhaling a mist;
• a liquid reservoir structure comprising a liquid chamber adapted to receive liquid to be atomized;
• a sonication chamber in fluid communication with the liquid chamber, wherein at least part of the liquid reservoir structure and the mouthpiece form the sonication chamber, the sonication chamber comprising an ultrasonic vibration device;
• and
• a capillary element arranged between the liquid chamber and the sonication chamber, wherein the capillary element comprises a central portion and a peripheral portion, the central portion having a U-shape cross section extending to the sonication chamber, the U-shape cross section having an inner portion and an outer portion, the inner portion of the U-shape cross section being in a first plane and in surface contact with the ultrasonic vibration device and the outer portion of the U-shape cross section extending from the inner portion in a direction along a second plane transverse to the first plane and being not in surface contact with the ultrasonic vibration device.
