Abstract
We report the first results of our INTEGRAL observations of the nearest spiral galaxy, M31. M31 has been a popular target for all telescopes. In the X-ray/gamma-ray wave band, we only have images of M31 with energies up to 10 keV. However, observations taken with BeppoSAX and Suzaku HXD have revealed that there is significant high-energy emission up to 100 keV. In 2008 January, we performed a 400ks INTEGRAL observation to obtain the first hard X-ray/soft gamma-ray image of M31. In this talk, we will present the preliminary results and compare with our own Suzaku HXD data.
