We constructed glass RPC modules for detecting K-L and muon in BELLE experi
ment. The modules have been installed in the instrumented iron yoke outside
of the solenoid coil and cover about 2000 m(2) of detectors. We report the
design and construction of the detectors, including the gas distribution a
nd exhaust system, the HV system, the readout electronics and DAQ system. T
he performance with cosmic ray and the e(+)e(-) collision data are presente
