The present invention relates to a microphone which includes: a case having an outer sound hole; a first printed circuit board coupled to the inner portion of the case and having an inner sound hole communicating with the outer sound hole; a MEMS chip mounted on the inner surface of the printed circuit board and disposed at the inner sound hole; a second printed circuit board coupled to the inner portion of the case and spaced apart from the first printed circuit board, and which includes connecting terminals on the outer surface thereof; a plurality of conductive connecting members electrically connecting the first printed circuit board to the second printed circuit board; and a spacing support disposed between the first and second printed circuit boards to support the first and second printed circuit boards with a space therebetween. The microphone can provide a sufficient rear chamber space and be efficiently assembled, and the shape and volume thereof can be conveniently varied if necessary.
