PROBLEM TO BE SOLVED: To provide a sound collection apparatus capable of carrying out more diversified sound collection. SOLUTION: The sound collection apparatus 1 is characterized in including: two single directivity microphones 2, the directivity axis of which is turnable around two rotary shafts a, b in parallel with each other; and support parts 21 for supporting the single directivity microphones 2 in a way of being movable for a prescribed interval on straight lines tying the two rotary shafts a, b. Through the configuration above, since the two single directivity microphones 2 are provided turnably around the two rotary shafts a, b in parallel with each other, the direction of the principal axis can individually be revised thereby allowing the sound collection apparatus 1 to cope with the diversified sound collection systems.
