A nondestructive beam-energy-spread monitor (BESM) using multi-stripline electrodes has been newly developed in order to measure and control the energy spread of a single-bunch electron beam at the 180-degree arc with a beam energy of 1.7 GeV in the KEKB injector linac. A proof-of-principle experiment was performed to verify the function of the BESM. The result shows that taking into account the second-order moment derived from the multipole-moment analysis, the energy spreads are estimated to
