The invention discloses an electronic mosquito-killing window screen, which has attractive integral appearance and long service life. The window screen comprises a window frame, a plurality of anode wires, and a plurality of cathode wires. Two ends of each anode wire and each cathode wire are fixed on two side frames of the window frame respectively. After connected, all anode wires are connectedwith an anode of a high-voltage direct current power supply. After connected, all cathode wires are connected with a cathode of the high-voltage direct current power supply. Each anode wire and each cathode wire have spring shape. Since each anode wire and each cathode wire have spring shape and each wire is rich in elasticity, the defect that the wire is easy to slack in the prior art is overcome, and the integral appearance of the electronic mosquito-killing window screen is greatly improved. Since the spring-shaped wires which are rich in elasticity are adopted, the wires do not need to betightened too much, thereby greatly improving the service life of the electronic mosquito-killing window screen.
