This report is some experimental results on electric discharge between crossing cylinders.　1. Flash over voltage between crossing cylinders is rarely effected by cross angle of them either in the case of impressed A. C. or impulse voltage. The discharge characteristic of the wire of diameter 15mm resembles closely that of the sphere gap of diameter 50mm.　2. The maximum potential gradient at the crossing cylinder's surface has been given as Bouwers' equation　Xm = Vn/(2ln･(r+(1/2)d)/r)･9/10 KV/cm,　where Xm : maximum potential gradient　Vn : impressed A. C. voltage (KV)　r : radius of cylinder (wire, rod) (cm)　d : gap length of crossing cylinders (wire, rod) (cm),　which is applied, by some modification, to the voltage range where corona is not significant.　3. When gap length is large, in the case of the positive impulse voltage (1.21*43.8μs), flash over voltage between crossing cyliners is found to be nearly equal to that of the rod electrode.　4. Impulse ratio of the crossing cylinders is about 1.2.　5. The electric field distribution about crossing cylinder electrodes has been experimentally found, using the similar arrangement of electrodes in the water tank.
