A shielding-type insulation detection structure includes an input power source, a first shielding layer, a second shielding layer, a first impedance unit, a second impedance unit and a detection circuit. The first shielding layer is electrically connected with a first terminal of the input power source. The second shielding layer includes a first sub-layer and a second sub-layer. The insulation layer is disposed between the first shielding layer and the second shielding layer. The first impedance unit is electrically connected between the first sub-layer and a second terminal of the input power source. The second impedance unit is electrically connected between the second sub-layer and the second terminal of the input power source. The detection circuit is used to detect a detection signal related to a voltage difference between the first sub-layer and the second sub-layer of the second shielding layer.
