摘要: A switching element is provided that realizes an stabilize a potential between the gates of multi-gates without increase in insertion loss, and antenna switch circuit radio frequency module each using element. The includes two ohmic electrodes 39, 40 formed on semiconductor substrate, at least gate 41, 42 disposed electrodes, conductive region 45 adjacent among field effective transistor being structured by region. has wider portion width than interposed one end thereof. distance narrower portion. Resistors 44, 46 are connected series through
