PROBLEM TO BE SOLVED: To provide a zoom microphone that is simple in the configuration and miniaturized and configured to be a so-called plug-in type. SOLUTION: The zoom microphone is provided with an L ch microphone 11L, a center microphone 11S and an R ch microphone 11R that are arranged parallel to a sound picking up face, resistors R1, R2 connected in series between a wire (a) of the L ch microphone 11L and a wire (b) of the R ch microphone 11R, a microphone side terminal s1 connected to the center microphone 11S, a resistor side terminal s2 connected to a connection part between the resistors R1, R2, and an earth terminal s3 connected to a reference level point via a capacitor C, and a changeover switch SW that is thrown to a position to connect the microphone side terminal s1 and the resistor side terminal s2 in a zoom mode or to a position to connect the resistor side terminal s2 and an earth terminal s3 in a stereo mode.
