Abstract: An electric insect killer includes a handle, an electric shock unit provided in the handle, a frame having a thickness to define a lower and an upper frame surface, and a plurality of conducting elements stretched in the frame. The electric elements are downward bent near two end portions to define a lower planar flapping surface and an upper U-shaped flapping surface relative to the lower and the upper frame surface. Each of the conducting elements may be extended perpendicular to or in the same direction as an extending direction of the handle, and may have a row of downward extended conducting wires provided at a lower side closer to the planar flapping surface to increase the contact area of the planar flapping surface.
