Provided is a sound insulation structure for an internal combustion engine that facilitates the assembly work, and minimizes the transmission vibrations and noises. The sound insulation structure for an internal combustion engine comprises a cover main body (21) disposed outside of a main body (10) of the internal combustion engine and covering at least a part of the engine main body, and a foam sound insulation member (22) made of a foam material and attached to an inner surface (21a) of the cover main body facing the engine main body. The foam sound insulation member covers a noise source (11) of the engine main body and abuts the engine main body or a component part (12, 14) attached to the engine main body at an outer periphery thereof so as to interpose the noise source. The engine main body or the component part includes a sound insulation wall (31-33) projecting therefrom so as to shield a junction part at which the foam sound insulation member abuts or adjoins the engine main body or the component part thereof and the sound insulation wall is covered by the cover main body.
