Abstract
A heater and a cigarette device having the heater is provided. The heater includes a base having a surface, an infrared electric-heating coating layer disposed on the surface of the base, and a conductor including a first conducting part and a second conducting part disposed on the surface of the base. Both of the first conducting part and the second conducting part are at least partially electrically connected with the infrared electric-heating coating layer. The first conducting part includes a first electric conducting spiral section, and the second conducting part includes a second electric conducting spiral section. A spacing between the first electric conducting spiral section and the second electric conducting spiral section is not zero. Through the first and second electric conducting spiral sections disposed on the surface of the base, a path of electric currents flowing through the infrared electric-heating coating layer of the base is shorter.
