  We report the synthesis and physical properties of the single crystals of
TaC, which are proposed to hold topological band structure as a topological
superconductor (TSC) candidate. Magnetization, resistivity and specific heat
measurements are performed and indicate that TaC is bulk superconductor with
critical temperature of 10.3 K. TaC is a strongly coupled type-II
superconductor and the superconducting state can be well described by s-wave
Bardeen-Cooper-Schrieffer (BCS) theory with a single gap. The upper critical
field (Hc2) of TaC shows linear temperature dependence, which is quite
different from most conventional superconductors and isostructural NbC, which
is proposed to manifest topological nodal-loops or type-II Dirac points as well
as superconductivity. Our results suggest that TaC would be a new candidate for
further research of TSCs.
