A stator coil heating apparatus and a stator coil heating method that are capable of effectively preventing a core from thermal deformation particularly caused due to a magnetic flux generated by a coil head, without the problem of heating temperature variation, and also shortening a time for the process of heating a stator coil, are provided.A stator coil heating apparatus A to heat a stator coil L wound around a circular core F, comprises: induction heating coil heads 1 and 11 that heat the circular coil L by generating an inductive effect acting from outside in the thickness direction of the core F, against circular winding coil bases La and Lb that are sticking out of end faces Fa and Fb of the core F in the thickness direction thereof; and shields 2 and 12 that block a magnetic flux generated by the coil heads 1 and 11, out of the end faces Fa and Fb of the core F in the thickness direction thereof.
