The present invention provides an automobile sound insulation panel which suitably implements a lightweight sound insulation panel with an expanded sound isolation-target frequency band and improved sound isolation performance. An automobile sound insulation panel SI includes a first panel member 1, a second panel member 2, and an elastic sheet member 3 positioned between the first panel member 1 and the elastic sheet member 3. The elastic sheet member 3 includes a first projection-recess part 4. The first panel member 1 abuts on respective upper opening edges of a plurality of recesses 4A that form the first projection-recess part 4. Individual air layers AG1 exist between the second panel member 2 and the elastic sheet member 3. A continuous air layer AG2 exists between the first panel member 1 and the elastic sheet member 3.
