We measured electrical resistivity on antiferromagnet Ce2Ir 3Ge5 under high pressure up to 8 GPa. It is shown that the Néel temperature (= 9.5 K) at ambient pressure decreased by increased pressure. The Néel temperature seems to be zero at a critical pressure Pc ≃ 2.0 GPa suddenly. The variation by higher pressure above 2.0 GPa does not seem prominence up to 8 GPa.
