Y₂C₃ is a superconductor whose T_c changes from 6 to 18K depending on the synthesis conditions. Since its electronic properties were unknown, we performed the electrical-property study by measuring the microwave complex surface impedance, Z_s, of Y₂C ₃ for different T_c's (13.9 and 15.5 K), and the resistivity and mean free path were determined in the normal state. We observed the typical behavior of a Drude metal in the Hagen-Rubens limit (ρ₁ ≫ ρ₂) in the normal state. We succeeded in observing the occurrence of superconductivity in the electrical property. Furthermore, we found that Y₂C₃ is a clean superconductor.
