The intermetallic compound Y${}_3$Pt${}_4$Ge${}_{13}$ has been synthesized by high-pressure high-temperature technique. It crystalizes with its own noncentrosymmetric type of crystal structure in the monoclinic space group $Cc$ and is superconducting below $T_c=4.5$ K. Thermodynamic properties as well as transport measurements were performed down to 0.4 K. The upper critical field is ${\mu }_0{H}_{c2}=3.8$ T, the lower one only ${\mu }_0{H}_{c1}=5$ mT. All observations are consistent with an $s$-wave symmetry single-energy gap for the superconducting phase.
