A stringed instrument has a body which is composed of a back case and a top case combined by screwing up screw receiving bosses of the back case to screw attaching bosses of the top case with a vibration absorber provided between a side wall of the back and a side wall of the top. Attached to the back case are string vibration parts such as a neck and a bridge base. The bridge base is exposed to the outside from an opening in the top case. Non-string vibration parts including a tape recorder and a speaker are attached to the top case. Thus, when string vibrations are transmitted from the back case to the top case, the central portion of the top of the top case becomes a loop where the vibration amplitude is maximum and the top vibrates greatly freely. Thus, according to the inventive stringed instrument, a musical sound of an increased volume with a warm tone quality containing sufficient overtones is obtained.
