The spark plug comprises:—a central electrode (2),—an insulating core (6) bearing the central electrode (2),—an external body (8) in which the insulating core (6) is mounted and which has a region (18) where the external body (8) is crimped onto the insulating core (6), and—a force sensor (30). The force sensor (30) is mounted at the periphery of the external body (8) between, on the one hand, a bearing element (38) secured to a first peripheral region of the external body (8) and, on the other hand, a second peripheral region (24) of the external body (8). The second peripheral region (24) of the external body (8)is further away from the crimping region (18) than the first peripheral region. The bearing element (38) is prestressed against the force sensor (30).
