1. An aerosol generating device for heating a cigarette to generate aerosol, the aerosol generating device comprising:
an inner wall configured to form an accommodating space for accommodating at least a portion of the cigarette;
a coil provided outside the inner wall, surrounding at least a portion of the accommodating space, and configured to generate an induced magnetic field;
a heating body provided in the accommodating space and comprising a ferromagnetic substance that generates heat by the induced magnetic field;
a supporting portion supporting the heating body and integrally molded with the heating body; and
an outer wall provided outside the inner wall and spaced apart from the inner wall,
wherein the inner wall supports the supporting portion and is integrally molded with the supporting portion, such that the heating body, the supporting portion, and the inner wall are integrally molded, and
wherein the coil is provided in a space between the inner wall and the outer wall and the coil is spaced apart from the inner wall and the outer wall.
