PROBLEM TO BE SOLVED: To provide an atomizer for ion generation which is suitable as an ion source of, for example, mass spectrometer, can be manufactured easily and accurately with a simple structure, can realize small size and light weight, and can suppress dead volume between the discharge side end part of the liquid sample and the atomizer, while improving widening of the separation peak of the liquid sample of very micro quantity and low velocity to improve detection sensitivity. SOLUTION: An atomizer 21 capable of impressing a high voltage is arranged at the discharge side end part of a liquid sample. This is an ion generation atomizer in which the liquid sample is sprayed from a nozzle 23 of the atomizer 21, and the atomized liquid droplet is ionized. The atomizer 21 is formed in thin plate shape. The nozzle 23 and the discharge side end part of the liquid sample are arranged in close contact. The dead volume between the discharge side end part of the liquid sample and the atomizer is suppressed. COPYRIGHT: (C)2005,JPO&NCIPI
