An automobile sound insulation panel includes a first panel member, a second panel member, and an elastic sheet member positioned between the first panel member and the elastic sheet member. The elastic sheet member includes a first projection-recess part. The first panel member abuts on respective upper opening edges of a plurality of recesses that form the first projection-recess part. Individual air layers exist between the second panel member and the elastic sheet member. A continuous air layer exists between the first panel member and the elastic sheet member.",
