The present invention relates to a heat-insulating sound-absorbing panel with excellent heat insulating performance (heat blocking performance) and sound absorbing performance (sound blocking performance). The heat-insulating sound-absorbing panel comprises: sound absorbing panels (2, 3) compression-molded in prescribed thicknesses (t1, t2); and a nonflammable sound-blocking sheet (4) of a prescribed thickness (t3) joined between the sound absorbing panels (2, 3) by an adhesive. Also, the heat-insulating sound-absorbing panel may comprise: a nonflammable sound-blocking sheet (4) of a prescribed thickness (t4) joined between the sound absorbing panels (2, 3); and a nonflammable sound-blocking sheet (4) of the prescribed thickness (t4) and a sound absorbing panel (6) sequentially joined to a back surface of the sound absorbing panel (3). Also, the heat-insulating sound-absorbing panel may comprise: a nonflammable sound-blocking sheet (5) of the prescribed thickness (t4) joined between the sound absorbing panels (2, 3); a nonflammable sound-blocking sheet (5) of the prescribed thickness (t4) and a sound absorbing panel (6) of a prescribed thickness (t5) sequentially joined to the back surface of the sound absorbing panel (3); and a nonflammable sound-blocking sheet (7) of a prescribed thickness (t7) and a sound absorbing panel (8) of a prescribed thickness (t8) sequentially joined to a back surface of the sound absorbing panel (6). Also, the heat-insulating sound-absorbing panel may comprise: a nonflammable sound-blocking sheet (4) of the prescribed thickness (t4) joined between the sound absorbing panels (2, 3); and a heat insulating sheet (9) of a prescribed thickness (t9) which is joined to a front surface of the sound absorbing panel (2), and has heat resistance of 800-1,500C. The nonflammable sound-absorbing sheet has a thickness of 1/5-1/25 of a thickness of the sound absorbing panel, and is made of at least one among paper, foil, a silica sheet, a silicon coated product, and a carbon sheet which are not burnt or melted by a flame or a high temperature.
