The invention discloses an inner plate of a tail door. The inner plate comprises an inner plate body, the inner plate body is provided with lightening holes which are symmetrically arranged relative to the symmetry axis of the inner plate body, and the structural performance of the inner plate body meets the preset requirement; the lightening holes comprise first lightening holes and second lightening holes which are symmetrically formed relative to the symmetry axis of the inner plate body; the first lightening holes and the second lightening holes are distributed in the axial direction of the symmetry axis of the inner plate body, and each of the first lightening holes and the second lightening holes is provided with an oblique edge which is oblique relative to the symmetry axis of the inner plate body; and the first lightening holes comprise two pairs of first triangular holes which are symmetrically arranged. According to the inner plate, the structural performance of the inner plate body is guaranteed, meanwhile, the weight of the inner plate body is reduced, and it can be guaranteed that the structural performance of the inner plate body meets the preset requirement through symmetrical arrangement of the lightening holes. The invention further discloses a tail door with the inner plate and an automobile with the tail door.
