Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a structure and method for lead wire connection capable of exactly electrically connecting conductors without soldering. SOLUTION: An electromagnetic acoustic transducer 1 comprises: a base 24 made of a magnetic material; a magnetic core 22 made of the magnetic material and protrudingly mounted on the base 24; a diaphragm 20 made of the magnetic material and supported at a distance from the tip of the magnetic core; a magnet 25 that constitutes a magnetic circuit together with the base 24, magnetic core 22 and diaphragm 20 and supplies a static magnetic field; a coil 23 that supplies an oscillating magnetic field to the magnetic circuit; and the like. Lead wires 23a, 23b of the coil 23 are electrically connected by resistance welding or thermal welding so as to be sandwiched by connection lands 50a, 50b and cover members 52a, 52b.
