The absorption spectra of CsCoCl3 under high magnetic fields were investigated. Sublattice splittings were observed in an exciton line and its cold and hot sidebands. The magnitude of splitting of the hot band was not equal to that of the cold magnon sideband but was equal to that of the exciton line. Consequently, the hot band was ascribed to the exciton creation at a thermally excited soliton.
