Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a fuel tank system capable of early detecting an abnormality of an oil supply SW by detecting the abnormality of the oil supply SW while an IGSW is turned off.SOLUTION: A fuel tank system 10A comprises: an ECU 32 into which an opening signal Sa of an oil supply SW 28 is input. The ECU 32 comprises: a main control section 78 controlling an engine of a vehicle; a main relay control circuit 76 turning off a main relay 72 when an IGSW 12 for operating start/stop of the engine is turned off; a SOAK time measurement circuit 94 capable of measuring an input time when the opening signal Sa is continuously input into the ECU 32 while the IGSW 12 is turned off or a non-input time when the opening signal Sa is not input into the ECU 32 in a state in which the oil supply SW 28 is turned on while the IGSW 12 is turned off; and a failure determination section 98 determining that the oil supply SW 28 is abnormal when the SOAK time is longer than failure determination time.
