We report on fabrication of a Coulomb blockade electrometer based on an ultrasmall YBa2Cu3O7-delta(YBCO) island coupled by tunnel junctions to two Sold electrodes. At temperatures below 0.5 K the low bias conductance was suppressed by the Coulomb blockade. The blockade could periodically be varied by the gate potential. An external magnetic field of up to 5 T strongly influenced the transport via the island but did not change the period of the gate voltage dependence.
