CdCr$$_2$$O$$_4$$ has the spinel structure, in which geometrical frustration exists between the Cr$$^{3+}$$ moments located at the corners of the tetrahedron. It shows an incommensurate antiferromagnetic ordering below $$Trm_N$$=7.8K with a characteristic wave vector of $$Q=(0, delta, 1)$$ ($$deltasim0.09$$). We first performed a 1D polarized neutron analysis and determined that the Cr$$^{3+}$$ moments has a planer anisotropy in the $$ac$$ plane, indicating that the magnetic structure is spiral. Finally, the 3D polarized neutron analysis using a CRYOPAD on TAS-1 at JRR-3 determined that the magnetic structure is elliptical spiral in the $$ac$$ plane with ellipsoid slightly elongated along the $$c$$ axis. The origin of the structure will be discussed.
