Abstract
A vaporizer comprises an absorber, a heating element, and a porous cover layer. The absorber is configured to absorb a material to be vaporized. The heating element is configured to heat and vaporize the material to be vaporized in the absorber, and includes a first electrode portion, a second electrode portion, and an electrically conductive connecting member connected between the first electrode portion and the second electrode portion. The porous cover layer covers at least a portion of the heating element without covering the first and second electrode portions. A ratio of an area of the porous cover layer to an area of the electrically conductive connecting member is defined as a covering ratio, which is at least 50%. A porosity of the porous cover layer ranges from 30% to 75%.
