PURPOSE: An apparatus for inspecting insulation layer of PDP panel is provided to inspect a quality or a spreading state of dielectric substance through a large territory by a nondestructive inspection with non-contact probe. CONSTITUTION: An apparatus for inspecting insulation layer of PDP panel comprises a first short bar(50) and a second short bar(55) to apply a standard voltage to all bus electrode of a PDP panel, a capacitance nearing sensor probe(60) for scanning a top part of a dielectric substance formed on the bus electrode in a non-contact method and outputting the change between the bus electrodes according to a change of a dielectric constant and a thickness of the dielectric substance as a voltage value using a capacitance, and a control part(90) for controlling the capacitance nearing sensor probe as well as deciding a state of the dielectric substance by the output voltage of the capacitance nearing sensor probe.
