    Abstract: A sensor has a sensor body (2) with a first face (2b) and a second face (2a) opposite to one another, and a circuit arrangement (5) supported by the sensor body (2) that includes: - a first electrical circuit pattern (6) on the first face (2b); - a second electrical circuit pattern (7) on the second face (2a); - connection means (14-14a, 15-15a), which electrically connect the first circuit pattern (6) to the second circuit pattern (7) and comprise at least one through hole (14-14a, 15-15a) that extends axially between the two faces (2a, 2b) of the sensor body (2), where extending over an inner surface of the at least one through hole (14-14a, 15-15a) is a layer of electrically conductive material (14a, 15a); - a plurality of terminals (10), for connection of the circuit arrangement (5) to an external system, the terminals (10) being electrically connected to at least one of the first circuit pattern (6) and the second circuit pattern (7). The at least one through hole (14-14a, 15-15a) is preferably closed at the second face (2a) of the sensor body (2) via a closing member (30) having a body (30a) that is at least in part pre-formed. The pre-formed body (30a) of the closing member (30) has a closing portion (31) having a perimetral or cross-sectional dimension, in particular a diameter, greater than a perimetral or cross-sectional 20 dimension, in particular a diameter, of the opening of the through hole (14-14a, 15-15a) at the second face (2a) of the sensor body (2). At least one portion (31, 32) of the pre-formed body (30a) of the closing member (30) is fixed in position in a fluid-tight way with respect to the corresponding hole (14-14a, 15-15a).
