Film plane.

The precise vertical plane in the camera at which the film surface is located. On many cameras this is marked on the top of the camera with a film plane mark.

Technically the film plane is actually curved and not a flat plane, because most lenses project an image as if onto a section of a large sphere, but film plane is what it’s traditionally called.

cf. film plane mark, focal plane, plane.
