Technologies for the next generation light sources based on energy-recovery linac (ERL) are under development in our group. Photocathode related technology is a key technology for the ERL based light sources. Temporal shape control of the photocathode gun generated electron beam is indispensable to generate ultra-small emittance electron beam. A 1300 MHz deflecting cavity has been developed for a temporal shape measurement of an electron beam from a 250-kV DC photocathode electron gun. The cavity is a rectangle shaped TM120 mode with the unloaded quality factor 
= 17660. The deflecting angle is 
9.5 mrad for the electron bunch with 50 ps with 134.7 W input RF power.
