The paper deals with the problem of eigenoscillations near the obstacle with the arbitrary sufficiently smooth shape of boundary immersed in three-dimensional waveguide of rectangular cross-section. Assumed that the guide and the obstacle are rigid. For a wide range of the obstacle geometry the existence of eigenwaves has been proved and their frequencies are embedded in the continuous spectrum.
