An insulating bobbin (10; 10A; 10B; 10C. 20, 30) for disposition between a stator core and a stator winding (50) of a stator of a rotating machine, the stator winding (50) being wound around the stator core by way of the insulating bobbin (10; 10A; 10B; 10C, 20, 30), the insulating bobbin (10; 10A; 10B; 10C, 20, 30) comprising a coil end section (11) at which an end portion of the stator winding (50) is disposed, a slot side section (12) forming a slot for winding thereon the stator winding (50), and a corner section (13; 13A; 13C) having a curved surface and connecting between the coil end section (11; 11C) and the slot side section (12; 12C), the corner section (13; 13A; 13C) having a first radius (r1) of curvature at a side closer to the coil end section (11; 11C) and a second radius (r2) of curvature at a side closer to the slot side section (12; 12C), the second radius (r2) of curvature being larger than the first radius (r1) of curvature. |
