AXEL is a high pressure xenon gas TPC detector which is under development for neutrinoless double beta decay search. We use the proportional scintillation mode with a new electroluminescence light detection scheme using Multi-pixel photon counter(MPPC) to achieve very high energy resolution with a large detector. The detector also has a capability of tracking and can reduce background. The project is in a R&D phase. We report a demonstration of the concept of AXEL with 10 L and 4 bar prototype chamber. Some studies of basic property of MPPC are also reported.
