PROBLEM TO BE SOLVED: To prevent thermal demagnetization of a permanent magnet or the loss of magnetism in the permanent magnet by blocking or reducing heat conduction to the permanent magnet that constitutes a rotor, in assembling the rotor of an axial-gap-type rotating electrical machine by welding. SOLUTION: The rotor 14 includes: a first pressing member 22 which supports a field part 20, a frame 26 which has a field part storing hole 24 and is welded to the first pressing member 22, a permanent magnet 28 stored in the field part storing hole 24, a magnetic substance 30 stored in the field part storing hole 24 in contact with the permanent magnet 28, and a second pressing member 32 which is welded to the frame 26 and fixes the permanent magnet 28 in the field part storing hole 24 by fixing the magnetic substance 30 in the field part storing hole 24.
