Summary:According to one embodiment, there is provided a gas cooled electric rotating machine in which a cooling gas is flowed through into a rotor (2) and a stator (3). The rotor (2) includes a pair of center hole conductors (211, 221) inserted into a center hole (201) along a center of rotation (L) while being electrically insulated from a shaft (20) and from each other, the center hole conductors (211, 221) including respective protruding parts (211A, 221A) protruding toward an end of the shaft (20). The rotor (2) includes a pair of end conductors (212, 222) provided at the end of the shaft (20) so as to be each electrically insulated from the shaft (20), the end conductors (212, 222) being electrically connected to side surfaces of the protruding parts (211A, 221A) of the pair of center hole conductors (211, 221), the side surfaces serving as electric connection surfaces.
