An electrode assembly for an electrosurgical instrument comprises an electrode tip (4) mounted on an elongate electrode stem (5), and an insulating housing (3), the housing having an elongate bore (8) formed therethrough. The bore (8) is such that the electrode stem (5) can be received within the bore with the electrode tip (4) extending from the distal end of the housing and a proximal portion (9) of the stem extending from the proximal end of the housing. An electrical lead (10) is located adjacent the proximal portion (9) of the stem, and a mass (11) of electrically conductive material forms an electrical connection between the lead (10) and the electrode stem (5). The mass (11) of electrically conductive material is of such a size that in addition to forming an electrical connection it also forms a mechanical stop preventing the electrode stem (5) from being moved distally with respect to the insulating housing.
