We report measurements of the heat capacity of pressure-induced superconductivity in an antiferromagnet CeRhSi3 under pressure up to P = 1.34 GPa. CeRhSi3 crystallizes into the tetragonal BaNiSn3-type structure without inversion center, which is the same as newly discovered superconductor CePt3 Si. At ambient pressure a pronounced anomaly in the specific heat is observed, indicating the transition to an antiferromagnetically ordered state at TN = 1.61 K. TN increases with increasing pressure below around P = 0.75 GPa and then decrease with increasing pressure. At P = 1.34 GPa, we confirmed the superconductivity at Tc = 0.45 K by the specific heat measurement, which was previously reported by the electrical resistivity measurement.
