Abstract
We present results on mid-infrared imaging and spectroscopic observations of the nearby late-type spiral NGC6946 with the Infrared Camera on board AKARI. Based on mid-infrared imaging with the S7 (7μm may be tools to measure the star-formation activity in remote galaxies if these ratios and their variations are well examined and established for a large sample.
