Abstract: The Milky Way is our home galaxy in the universe. However, human beings do not know much of our home galaxy about its structure and physical properties. The author and his cooperators have spent a decade to reveal the largescale of magnetic fields of our Milky Way galaxy. They achieved a significant progress. Originally only knowledge of magnetic fields in the local galactic area of a few thousand lightyears was there. Now, a global magnetic field structure of our Milky Way, a scale of tens of thousand lightyears, is known. Here they report their efforts and results.

Key words: Milky Way, magnetic fields, radio, Faraday rotation, pulsar
