A connector comprising: a plug contact of cylindrical shape, the plug contact being conductive and having a recess extending along a fitting axis; and an inner contact (18, 28, 38, 48, 58, 68, 78) formed of a plate member, the inner contact being conductive and inserted into the recess, wherein the plate member includes: a first constituent portion (18A, 38A, 58A, 68A, 78A) including a contact portion that is elastically displaceable in a direction orthogonal to the fitting axis and that comes into contact with the plug contact in the recess; a second constituent portion (18B, 28B, 48B) including a pressing portion that is elastically displaceable in a direction orthogonal to the fitting axis independently of elastic displacement of the contact portion of the first constituent portion; and a coupling portion (18C, 28C, 38C, 48C, 58C, 68C) that couples the first constituent portion and the second constituent portion such that the first constituent portion and the second constituent portion are apart from each other along the fitting axis, and part of a connection target of sheet-like shape in which a flexible conductor (15B, 15E) is exposed on at least one surface is sandwiched between the pressing portion and an inner surface of the recess in a direction orthogonal to the fitting axis, and the inner surface of the recess comes into contact with a front surface of the connection target while the pressing portion comes into contact with a back surface of the connection target, whereby the plug contact is directly electrically connected to the flexible conductor in a case where the flexible conductor is exposed on the front surface of the connection target, and the plug contact is electrically connected to the flexible conductor via the inner contact in a case where the flexible conductor is exposed on the back surface of the connection target. a plug contact of cylindrical shape, the plug contact being conductive and having a recess extending along a fitting axis;
