1. A rollable electronic apparatus being windable, comprising:
a flexible electronic device; a flexible cable; a circuit substrate; and a support body having a tubular body,
wherein the flexible electronic device includes a terminal portion,
the flexible cable connects the terminal portion and the circuit substrate,
a drive circuit is mounted on the circuit substrate,
the flexible electronic device and the flexible cable are wound on an outer circumferential surface of the support body by rotating the support body,
the support body has, in a cross-sectional view, two curved portions and a planar portion connecting the two curved portions, and
the circuit substrate is stored in the planar portion in a state in which the flexible cable is wound.
