There is provided a rotating electrical machine capable of suppressing backlash of a magnet in the trust direction and suppressing an axial variation in the fitting position of the magnet. A magnet holder 19 used for a motor 1 has a holder base 31 fixed to a rotary shaft and a plurality of holder arms 32 projecting from the holder base 31 in the extending direction of the rotary shaft. The holder base 31 has sidewall portions 53 between adjacent holder arms 32. On each sidewall portion 53, there is formed an inner end surface 53a opposed to an axial end portion 17c of the magnet 17. Projections 55 are formed on the inner end surfaces 53a, and the projections 55 are pressed and crushed by being brought into contact with the axial end portion 17c of the magnet 17. The magnet 17 is fitted in the holder arms 32 while pressing and crushing the projections 55. When the projections 55 are pressed and crushed, accumulated dimensional tolerance of the magnet 17 and the like is absorbed, and as a result, backlash of the magnet 17 in the thrust direction is suppressed.
