PURPOSE: To provide a piezoelectric electroacoustic transducer that users burrs to prevent terminal from floating and eliminates a defect such as floating at mounting and to provide its manufacturing method. CONSTITUTION: The piezoelectric electroacoustic transducer is provided with a square piezoelectric diaphragm 1 that is subjected to bending vibration, a resin-made case 10 with supports for supporting the piezoelectric diaphragm 1, insert terminals 11, 12 whose inner connections 11a, 12a are exposed to the supports and whose external connections 11b, 12b are exposed to the outer face of the case 10, a conductive adhesive for connecting the electrodes and the terminals, and an elastic sealing agent 15 for sealing the gap between the piezoelectric diaphragm and the case. The terminals 11, 12 are terminals pressed from a metallic plate, the burr forming faces of which are directed to be lower sides, burrs at both side edges of the inner connections 11a, 12a are embedded in the inside of the supports of the case 10, external connections 11b, 12b of the terminals 11, 12 are folded toward the bottom face via the side face of the case 10.
