An electronic censer includes a censer body, an incense branch and a circuit board. The circuit board is received in the censer body. The incense branch is positioned on the circuit board and includes a heat dissipating board, a light-emitting diode, a first incense core, a second incense core enclosing the first incense core and a reflecting layer on a periphery of the second incense core. A tubular passage is defined between a periphery sidewall of the first incense core and a sidewall of the heat dissipating board to receive liquid fragrance therein. Heat generated by the LED is transferred to the liquid fragrance via the heat dissipating board. Vapor of the liquid fragrance and light of the LED leave the electronic censer via a top of the incense branch.
