The present invention provides a high-voltage measuring device capable of providing sufficient electric isolation between resistors and between resistors and a voltage measurement circuit without necessity of enlarging a size of a substrate for carry thereon the circuit. A high-voltage measuring device mounted on a substrate, comprising a high-voltage input terminal pair, a measuring terminal pair, a voltage measuring circuit having input terminals connected to the measuring terminal pair, and two resistive parts. One of the resistive parts electrically connects one of high-voltage input terminal pair and one of measuring terminal pair. The other of resistive parts electrically connects between the other of high-voltage input terminal pair and the other of measuring terminal pair. Each of the resistive parts comprises a series circuit of at least one high resistance resistor and at least one low resistance resistor, wherein a distance between the high resistance resistors in each of the resistive parts is larger than that between the low resistance resistors.
