         3 . The cartridge according to  claim 1 , wherein the chamber inlet is shaped to define a slot that is elongated in a longitudinal direction of the wick. 
     
     
         4 . The cartridge according to  claim 3 , wherein the chamber inlet has a width of about 1.8 mm to about 1.9 mm relative to the longitudinal direction of the wick. 
     
     
         5 . The cartridge according to  claim 2 , wherein the chamber inlet has a height of about 1.5 mm to about 1.6 mm relative to a radial direction of the wick. 
     
     
         6 . The cartridge according to  claim 1 , wherein the chamber inlet comprises a portion formed to gradually increase in cross-sectional area in a direction extending from the chamber inlet toward an interior of the second chamber. 
     
     
         7 . The cartridge according to  claim 1 , wherein the chamber outlet is shaped to define a slot that is elongated in a longitudinal direction of the wick, and overlaps a portion of the wick in an air flow direction between the chamber inlet and the chamber outlet, and a center axis of the chamber outlet is located below the center axis of the wick. 
     
     
         8 . The cartridge according to  claim 1 , further comprising:
 a first container shaped to include the first chamber and an inflow passage formed to be separated from the first chamber and to permit communication between an outside and the chamber inlet:   a frame located under the first container, the frame shaped to define the chamber inlet, the chamber outlet, and the second chamber; and   a second container coupled to a lower side of the first container, the second container accommodating the frame therein and being shaped to define a cartridge outlet in communication with the chamber outlet.   
     
     
         9 . The cartridge according to  claim 8 , wherein the frame is shaped to define a frame passage extending curvedly from the inflow passage toward the second chamber to connect the inflow passage to the chamber inlet. 
     
     
         10 . The cartridge according to  claim 8 , wherein the frame comprises a first inner inclined surface formed below the chamber outlet, wherein the inclined surface extends from a bottom of the frame to the chamber outlet to guide air from the second chamber to the chamber outlet. 
     
     
         11 . The cartridge according to  claim 10 , wherein the first chamber is open downwards,
 wherein the second chamber is open upwards, and   wherein the cartridge further comprises a plate disposed between the first container and the frame to cover an opening in the first chamber and an opening in the second chamber,   wherein the plate comprises a second inner inclined surface extending slantedly from a lower surface thereof and covering the opening in the second chamber and extending toward a periphery of the chamber outlet to guide air from the second chamber to the chamber outlet.   
     
     
         12 . The cartridge according to  claim 9 , wherein the frame is shaped to define an outlet port having therein the chamber outlet and protruding from the frame to surround a periphery of the cartridge outlet and contact an inner side surface of the second container. 
     
     
         13 . The cartridge according to  claim 12 , wherein the outlet port and the inner side surface of the second container that is in contact with the outlet port are formed to be slanted at inclinations corresponding to each other. 
     
     
         14 . A cartridge comprising:
 a first chamber structured to store liquid:   a second chamber shaped to define a chamber inlet and a chamber outlet, wherein the chamber outlet is located at a side of the second chamber that is opposite to that of a location of the chamber inlet:   a wick that is elongated in one direction and is positioned between the chamber inlet and the chamber outlet in the second chamber, wherein the wick is in communication with the first chamber; and   a heater configured to heat the wick,   wherein the chamber inlet faces the wick, and is formed to be longer in a longitudinal direction of the wick relative to a radial direction of the wick.   
     
     
         15 . An aerosol-generating device comprising:
 a cartridge comprising:
 a first chamber structured to store liquid; 
 a second chamber shaped to define a chamber inlet and a chamber outlet, wherein the chamber outlet is located at a side of the second chamber that is opposite to that of a location of the chamber inlet;
