In order to study non-zero spin excitations of the recently proposed α-cluster condensation in the self-conjugate 4n nuclei, spatial deformation is introduced into the model wave function of the α-cluster condensate. The rotational band states of ^8Be are investigated as a first step of a test case for the study of the deformation of the α-cluster condensate. Calculations reproduce well the binding energy of the 0^+ ground state and also the excitation energy of the 2^+ state. Our 0^+ wave function is found to be almost exactly equal to the 0^+ wave function obtained by the generator coordinate method using Brink's 2α wave function. The study shows that both the 0^+ ground and 2^+ excited states can be considered as having a gas-like (i.e. weakly bound) 2α-cluster structure. As for the 0^+ ground state, the change of the wave function, due to the introduction of the deformation, is found to be very small.
