To provide an electroacoustic transducer capable of providing a reproduction sound of high sound quality with a wide reproduction frequency band.

The electroacoustic transducer includes: a housing 1 having a sound emitting hole 12a for emitting a sound wave to the outside; a diaphragm 3 of a laminated structure including a layer including a wooden sheet 31; and a drive section 4 for vibrating the diaphragm 3. The diaphragm 3 is provided inside the housing 1 with the fiber direction of the wooden sheet 31 directed in the axial direction L of the sound emitting hole 12a. The inside of the housing 1 is partitioned into two spaces S1 and S2 by the diaphragm 3. The space S1 is communicated to the outside via the sound emitting hole 12a, and the drive section 4 is built in the space S2. Then, the diaphragm 3 uses the wooden sheet 31 as a surface layer, and the wooden sheet 31 is directed toward the space S1.
