An insulation inspection apparatus includes a chamber in which a stator with a winding can be stored, an electrode movable along the outer circumference of a coil end of the stator winding, a voltage application unit applying voltage between the coil end and electrode, a sensor unit sensing leakage current and/or voltage drop between the coil end and electrode, and a pressure reduction unit reducing the pressure in the chamber.
