Abstract: A nitrous acid generator includes a treatment vessel having an inner space being capable of holding a liquid; a gas supplier supplying a gas to the inner space such that the gas forms a bubble in the liquid, the gas containing oxygen and nitrogen; a plasma generator including a first electrode, a second electrode, and a power supply for applying a voltage therebetween, the plasma generator generating plasma in the bubble, the plasma producing nitrogen oxide including nitrogen monoxide and nitrogen dioxide; a gas-liquid contact member to which the nitrogen oxide and the liquid are introduced from the treatment vessel, the gas-liquid contact member causing the nitrogen oxide to be dissolved in the liquid while the nitrogen oxide and the liquid pass through the gas-liquid contact member; and a cooler cooling the nitrogen oxide and the liquid while the nitrogen oxide and the liquid pass through the gas-liquid contact member.
