Study of afterpulsing events gives us an information of recovery time of Multi-Pixel Photon Counter (MPPC), which can be obtained by measuring the amplitude and the time interval between an afterpulse and its original pulse. It is important to measure the recovery time for investigating the internal mechanism of MPPC and to design detectors with this device. We have developed a waveform-analysis method to discriminate the pulses. As a result, recovery time and its bias dependency were obtained for three different types of MPPC.
