Provided is a sound absorption panel that can satisfy the heat resistance properties and melting/dripping resistance properties required inside of a railroad vehicle. A mixed sound absorption panel (10) comprises five sheets of first through fifth glass cloths (13-17) that are stacked on an aluminum substrate (11). The edge section of the fifth glass cloth (17) is affixed to the rear surface of the substrate (11) using an adhesive, and the first through fourth glass cloths (13, 14, 15, 16) are fastened using staples. In other words, the first glass cloth (13) and the substrate (11) are fixed using an adhesive, and this adhesive is prevented from melting by the five sheets of the first through fifth glass cloths (13-17). The adhesive that fixes the edge section of the fifth glass cloth (17) at the other surface of the substrate (11) is prevented from melting by the five sheets of the first through fifth glass cloths (13-17) and the substrate (11).
