A DC voltage detector for detecting the presence of a DC voltage in an object under detection (21) by bringing a detection electrode (11) provided inside a housing (23) near the object under detection (21), said DC voltage detector being provided with an AC generation unit (12) for generating an AC current corresponding to the DC voltage by varying a capacitance between an inter-electrode stray capacitance (C1) formed between the object under detection (21) and the detection electrode (11) and a floating earth capacitance (C2) formed between an internal shield (30) of the housing (23) and the ground. |
