PROBLEM TO BE SOLVED: To provide a structure of a sound insulation wall corner column capable of increasing sound insulation performance by eliminating the influence of sound bridge in a sound insulation wall corner part, being satisfactorily finished, and facilitating its designing, manufacture, and construction and having sufficient strength for attaching a face member. SOLUTION: This sound insulation wall corner column in, for example, an L-shaped corner is provided with a first long substrate angle bar 2 being a substrate for mounting the face members 7, 7 whose each side faces a room r1 on one side and which cross orthogonally, a second long substrate angle bar 3 being a substrate for mounting the face members 7, 7 whose each side faces a room r2 on the other side and which cross orthogonally, and a vibration isolation member 6 serving also for holding positional relation for connecting both of these substrate angle bars 2, 3 mutually in a manner for holding positional relation of them. The vibration isolation member 6 is composed of a piece-like member, a plurality of vibration isolation members are provided at an interval in the vertical direction, and each vibration isolation member 6 connects both of substrate angle bars 2, 3.
