The present invention relates to a soundproof panel fixing device for a roof of a tunnel soundproof wall. According to the present invention, a pillar is standing along both sides of a road and installed, a side wall frame is arranged between the pillar and a neighboring pillar in a vehicle driving direction to block a noise source, and a roof frame is formed by connecting a side wall frame and a side wall frame, opposing each other, by a beam, while a soundproof panel is coupled to the beam, in a tunnel soundproof wall. The soundproof panel is fixed by a panel fixing device fixed to the beam. The panel fixing device includes: a vertical piece installed in a road width direction while standing in the beam vertically to be fixed thereto; a panel fixing frame fixed to the vertical piece through a fastening device, having a guide groove into which a nut is inserted into the center in a longitudinal direction to be engaged and fixed, and having a seating surface to allow the soundproof panels to oppose, to be placed, and to be seated in both sides of an upper surface while the guide groove is provided as the center; a cover member placed on an upper portion of a ″+″ edge in contact with an edge of a soundproof panel in a plurality of soundproof panels placed on the seating surface and allowing four pressing portions formed in an edge of a bottom surface to be in contact with four soundproof panel edges; and a locking bolt passing through the center of the cover member to be fastened to the nut to allow the cover member to press and fix each edge of the soundproof panel.
