Abstract We report the detailed physical properties of YRu$_{3}$Si$_{2}$ with the Ru kagome lattice at normal and superconducting states. The results of resistivity and magnetization show that YRu$_{3}$Si$_{2}$ is a type-II bulk superconductor with $T_{\rm c}\sim 3.0$ K. The specific heat measurement further suggests that this superconductivity could originate from the weak or moderate electron-phonon coupling. On the other hand, both large Kadawaki–Woods ratio and Wilson ratio indicate that there is a strong electron correlation effect in this system, which may have a connection with the featured flat band of kagome lattice.
