PROBLEM TO BE SOLVED: To improve productivity and a quality in bonding of a voice coil and a damper or the like in a method of manufacturing an electroacoustic transducer to be used for audiovisual equipment or the like. SOLUTION: In the method of manufacturing the electroacoustic transducer, an ultraviolet curing type reactive twin pack adhesive 9a is used as an adhesive, the bonding part of the voice coil 7 and the damper 8 is coated with the adhesive and afterwards irradiated with ultraviolet rays from a lower part by using an optical fiber 10, an internally mirror-finished metallic die 11, and the like. Thus, the reactive twin pack adhesive is cured without being dropped or oozing out during its application, a magnetic gap defect is suppressed, curing is progressed by the irradiation with ultraviolet rays and assembly in the next process is made possible without waiting for complete curing and productivity is improved.
