To provide an engine hood for a construction machine that is able to reduce a welding volume without decreasing rigidity and excellent in appearance quality.SOLUTION: An engine hood for a construction machine is composed of: a cover member 2 forming an outer shell for an engine hood 1; and a structure member 3 disposed inside the cover member 2. The structure member 3 has: a base frame 4 formed in a frame shape so as to match an opening of an engine room; and a space frame 6 composed of a plurality of U-shaped bent materials 5 mounted on the base frame 4. The cover member 2 has: a cover 7 having a U-shaped cross-section so as to cover the opening of the engine room; and a flange 8 circumferentially formed along an edge part of the cover 7. The cover 7 of the cover member 2 is attached to the space frame 6 of the structure member 3 by means of a mastic adhesive M. The flange 8 of the cover member 2 is attached to the base frame 4 of the structure member 3 by means of an adhesive S for structure.SELECTED DRAWING: Figure 4
