  An upgrade of the Near Detector of the T2K long baseline neutrino oscillation
experiment, ND280, has been proposed. This upgrade will include two new Time
Projection Chambers, each equipped with 16 resistive MicroMegas modules for gas
amplification. A first prototype of resistive MicroMegas has been designed,
built, installed in the HARP field cage, and exposed to a beam of charged
particles at CERN. The data have been used to characterize the performances of
the resistive MicroMegas module. A spatial resolution of 300 $\mu m$ and a
deposited energy resolution of 9% were observed for horizontal electrons
crossing the TPCs at 30 cm from the anode. Such performances fully satisfy the
requirements for the upgrade of the ND280 TPC.
