摘要：
A stereo microphone has four condenser microphone units having respective directional axes in the same horizontal plane. The four units each have unidirectivity and a quadrangular shape viewed from the direction of the directional axis. The units are disposed by rotating the directional axes of adjacent units by 90°. A pair of two units diagonally positioned and having the directional axes directed at 180° to each other collaborate with each other to form a pair of bidirectional microphone units.
