To provide an electrode structure for electroacoustic transducer, capable of securing a high contact pressure at an end part contact part and improving the reliability in electrically connected parts.

A coil-like connection terminal 24 composed of a conductive wire for electrically connecting the electroacoustic transducer and a circuit board is provided with a large-diameter side winding part 31 on a first end side, a small-diameter side winding part 32 on a second end side, and an intermediate helical part 33, wound so as to gradually reduce the winding diameter between the large-diameter side winding part 31 and the small-diameter side winding part 32. The inside diameter of the large diameter side winding part 31 is formed so as to be smaller than the outside diameter of the intermediate helical part 33 and that of the small-diameter side winding part 32. On the outer side end face of the large-diameter side winding part 31 and the small-diameter side winding part 32, at least three points divided equally in the circumferential direction are formed so as to be located on a first plane P1 and a second plane P2 which are orthogonal to the axis L1 of the coil-like connection terminal 24.
