The elastic constant of the vortex lattice is measured in order to estimate the superconducting volume fraction of La1.875Ba0.065Sr0.060CuO4 which undergoes the structural phase transition to the low-temperature orthorhombic (Pccn) phase. The step like change in the elastic constant of c44 mode of the vortex lattice is clearly observed below Tc, and the saturated value of the elastic constant of the vortex lattice is 68% of the theoretical result for the full-Meissner state. This experimental result indicates that, probing with the vortex lattice, the superconducting volume fraction seems to be about two over three under the so-called stripe order in the Pccn phase.
