The observations of the H13CO+(J=1-0) line emission were carried out using the Nobeyama 45 m telescope and Nobeyama Millimeter Array. Our combined image of the interferometer and single-dish data depicts detailed structures of the dense envelope within the core. We found that the core has a radial density profile of n(r) prop. r^-p and a reliable difference in the power-law indices between the outer and inner regions of the core: p~2 for r >= 4000 AU and p ~ 1.5 for r <= 4000 AU}.
