We performed near-infrared line mapping of the supernova remnant IC 443 with the IRSF 1.4-m telescope, using the narrow-band filters tuned for [Fe II] 1.257 µm, [Fe II] 1.644 µm, and Paβ. We detected the [Fe II] and Paβ emissions from a very wide area of the observed region (30^‧ ×35^‧). These line intensity maps re…
