A theory of the exciton spectrum in the cylindrical nanotube is proposed in the paper. The spectrum of bound exciton states in a nanotube is obtained in the framework of rectangular potentials and electron and hole effective masses within the Bethe method.

The energy of the exciton ground state calculated for the InP/InAs/InP nanosystem is in good correlation with experimental data.
