To provide an electron beam device enabled to obtain multi-beam by using an electron gun having one cathode, and to provide a manufacturing method of a device using the electron beam device.
The electron beam device irradiates an electron beam emitted from a cathode 63 having a plurality of protrusions to a plurality of openings of a plate with openings 3, and reduce-projects the electron beam passed through the openings on a sample. The plurality of openings on the plate with openings 3 are formed by etching a Si single crystal plate 21. The plurality of openings on the plate with openings 3 can be formed by metal coating. A square nock hole, for the positioning of θ-direction, is formed to the plate with openings 3, or the outer form of the plurality of openings on the plate with openings 3 has sides which are parallel with X-axis or Y-axis.
