A porous heating body includes a porous body having a first porous portion, a second porous portion and a third porous portion successively disposed in the porous body along a lengthwise direction of the porous body. A cross-sectional area of the first porous portion and a cross-sectional area of the third porous portion are both larger than a cross-sectional area of the second porous portion along a widthwise direction of the porous body. A heating element extends along the lengthwise direction of the porous body is disposed on the porous body. The heating element includes a heating portion. At least one portion of an extension length of the heating portion is overlapped with an extension length of the second porous portion. The porous body is shaped to enhance conductivity of liquid tobacco in a middle thereof, and storing liquid tobacco for replenishing at two bulge ends thereof.
