A holder is for a small-sized acoustic element and a mounting structure for the same allowing mounting to a casing with a sound hole in a side surface thereof without involving a substantial increase in the thickness of a portable communication apparatus. The holder for a microphone has a cylindrical portion for holding the outer peripheral surface of a small-sized acoustic element. The cylindrical portion is equipped with an inwardly directed flange adapted to be engaged with a holed surface of the small-sized acoustic element and constructed of an annular rubber-like elastic member. Further, the cylindrical portion is provided with a groove-shaped sound hole whose one end is open in the inner peripheral surface of the inwardly directed flange and whose other end is open in the outer peripheral surface of the cylindrical portion, thus communicating with both the holed surface of the small-sized acoustic element and the sound hole formed in a side surface of the casing of the portable communication apparatus.
