To provide a small and inexpensive lightning arrester without installing a metal fitting for making tips of a T-shape coaxial connecting pluge and a coaxial cable of λ/4 into a short circuit.
One end of a coaxial cable 32 for antenna connection is fixed to an upper face of a ground plate 31, and one end of a coaxial cable 38 is fixed for communication machine connection. Tip parts of the coaxial cables 32 and 38 are bent in directions which approach mutually and center conductors 32a and 38a are connected. One end of the coil 42 for lightening is soldered to a connection. A metal wire whose electric length is about λ/4 is wound to the coil 42, and input impedance is set to a value which is more closer to input impedance of the coaxial cables 32 and 38. An insulting board 43 is disposed between the coil 42 and the ground plate 31. The other end of the coil 42 is fixed to the ground plate 31 through a lug plate 45. A lug plate 48 fitted to a tip of a ground wire 47 is fixed to the ground plate 31 by a screw 49.
