The thermal expansion and crystal structure of A-type carbonate apatite with the monoclinic symmetry was investigated using the neutron powder diffraction at room temperature, 200, 300, 400 and 500 $^{circ}$ C. The -axis and -axis lattice parameters were 0.9568 and 0.6868 nm at room temperature, and those were linearly increased with the increase of temperature. It was found that the linear thermal expansion coefficient of -axis was 1.3110 $^{-5}$ / $^{circ}$ C and -axis 8.0710 $^{-6}$ / $^{circ}$ C.
