PROBLEM TO BE SOLVED: To separate and extract individual sound sources by inferring a sound source direction, using two bidirectional microphones and one omnidirectional microphone, and switching zones without having to move the microphone physically. SOLUTION: A sound pickup and sound source separating device comprises a plurality of directional microphones 1, 2 of directions for different directivities from each other, one omnidirectional microphone 3, a directivity-varying means 4 for generating a signal obtained by weighted summing by a weighted summing coefficient set in different combinations of directions of the directivity, based on sound pickup signals from the respective microphones, a sound source direction inferring means 7 for inferring the sound source direction, based on the signal obtained by weighted summing the respective weighted summing coefficients, and a directivity-selecting means 6 for selecting the weighted signal by the weighted summing coefficient based on the inferred sound source direction.
