To provide a rotating machine which improves the cooling efficiency.

In an external cooling system of rotating machine 1 which makes a motor frame 4 hold a stator core 31 on which a coil 32 is wound and also radiates the heat generated in the above coil 32 from the above motor frame 4 via the above stator core 31, an end mold 6 is made to contact with coil ends 32a projected from both axial ends of the stator core 31 and to contact with the inner face of the above motor frame 4, and also fillers higher in heat conductivity than the resin are mixed in the resin forming the end mold 5.
