An electrosurgical instrument has a handpiece, an elongate shaft (22) mounted to the handpiece and including electrical supply conductors (24, 26) and, located at the distal end of the shaft, an active electrode (12) and a return electrode (14). Housed at the distal end of the shaft is a frequency up-converter in the form of a spark-gap device (24A, 26A, 36) which acts as a pulse generator operable in conjunction with a resonant output structure (12, 14, 16, 40, 42) to convert energy supplied via the electrical supply conductors at 1 MHz or lower to an alternating electrosurgical signal at a frequency of at least 500 MHz.
