We present a phase diagram for the antiferromagnetism and superconductivity in Ce2RhIn8 probed by In-NQR studies under pressure (P). The quasi-two-dimensional character of antiferromagnetic spin fluctuations in the paramagnetic state at P=0 evolves into a three-dimensional character because of the suppression of antiferromagnetic order for P>P-QCP similar to 1.36 GPa (QCP: quantum critical point). Nuclear-spin-lattice relaxation rate 1/T-1 measurements revealed that the superconducting order occurs in the P range 1.36-1.84 GPa, with maximum T-c similar to 0.9 K around P-QCP similar to 1.36 GPa.
