Title: ELECTRONIC DEVICE
Abstract:
An electronic device (100) is provided with a printed wiring board (1) that has first wiring line (L1) and a second wiring line (L2). A first semiconductor device (11), which has a first terminal (P1) and a second terminal (P2), and a PTC resistor (RP), which contains a PTC substance, are mounted on the printed wiring board (1). One end of the PTC resistor (RP) and the first terminal (P1) are connected to each other by the first wiring line (L1). The other end of the PTC resistor (RP) and the second terminal (P2) are connected to each other by the second wiring line (L2). The first semiconductor device (11) measures the temperature of a region where the PTC resistor (RP) is arranged on the basis of the sense voltage (VS) between the first terminal (P1) and the second terminal (P2).
