Patent number: 9520278Abstract: An object is to mix multiple liquids sufficiently and then nebulize the mixed liquids while maintaining the nebulizing efficiency. A nebulizer includes a first inner tube disposed inside an outer tube and having therein a first sample passage through which a first liquid sample flows, a second inner tube disposed inside the outer tube in parallel with the first inner tube and having therein a second sample passage through which a second liquid sample flows, a membranous member disposed with a gap between the membranous member and sample outlets formed at respective ends of the inner tubes.
