A power converter which can prevent an erroneous detection even when a flow rate of a refrigerant is low and a vehicle having the power converter mounted therein are provided. A first inverter circuit including: an element group constituted by six transistors; six diode temperature sensors at least one of which is provided for each transistor to detect a temperature of the transistor; and a high arm-side refrigerant flow passage and a low arm-side refrigerant flow passage in which a refrigerant for cooling the transistors flows is provided. In a failure detection device of the first inverter circuit, a failure determination member selects two diode temperature sensors among the plurality of diode temperature sensors, which detect temperatures of two adjacent transistors, as an adjacent sensor pair, and determines a failure of any one of the plurality of diode temperature sensors using detection values of the adjacent sensor pair.
