An antiferromagnet CeNiGe3, which exhibits a quantum critical point at PC ∼ 6 - 7 GPa, shows the superconductivity in wide pressure range of 1.7 - 9.3 GPa. In addition to the superconductivity around PC, the sharp superconducting transition can be observed by both the resistivity and the susceptibility measurements at lower pressure region far apart from PC, where 4f-localized picture seems to be still dominant. Such a superconductivity is a first example in the f-electron systems.
