Hollow structure film, circuit board, antenna substrate, and method for manufacturing a hollow structure film

Abstract

A hollow structure film (1) having a hollow structure comprises a first base (11) on a sheet, a second base (12) on a sheet that overlaps the first base (11), and a plurality of supporting members (20) provided between the first base (11) and the second base (12). The first base (11) has a first opposing surface (11a) facing the second base (12). The second base (12) has a second opposing surface (12a) facing the first base (11). At least a portion of the plurality of supporting members (20) forms a continuous supporting member (23) that extends from the first opposing surface (11a) to the second opposing surface (12a).
