Abstract
A semiconductor device has a configuration wherein a resistor that restricts overvoltage is inserted between an input terminal and the drain of JFETs, and the resistor is disposed on the JFETs. Also, the resistor is formed contiguously and integrally with a spiral form high breakdown voltage high resistance element that configures a resistive voltage divider circuit.
