Kepler's supernova remnant is a special type-Ia in the meaning of historically observed (400 years old). It has been studied well from both observational and theoretical aspects. Morphological signatures have been observed in radio, infrared, optical and X-ray bands. Some theories have predicted a measurable flux at TeV-gamma rays by the Imaging Cherenkov Atmospheric Telescopes. Here, we report on observations carried out in 2005 April by CANGAROO-III. We did not observe any statistically significant excess around this region. Limitation on the allowed parameter range in cosmic-ray theory are discussed.
