PROBLEM TO BE SOLVED: To provide a small-sized piezoelectric resonator that is easily housed in a package. SOLUTION: The piezoelectric resonator (10) of a tuning fork shape includes two parallel vibrating arms (12, 14), connected to each other by a linking part (16), from which protrude a central arm (18) located between both vibrating arms (12, 14), the vibrating arms (12, 14) carrying first electrodes (20, 22) to make them vibrate, these electrodes (20, 22) being connected to connection elements (28, 30) carried by the central arm (18), wherein a slot (80) has been cut within the linking part (16) opposite to the central arm (18) and wherein second electrodes (82, 84) have been arranged along the slot (80).
