Abstract

This invention provides an electron beam irradiation device employing a material containing a Ti-A1 intermetallic composite as the material of an electron beam permeable window for allowing passage to the outside of a chamber of an electron beam generated in the chamber. Also, this invention provides a method of manufacturing an electron beam permeable window containing a Ti-A1 intermetallic composite by manufacturing a window-frame mounted titanium foil by fixing titanium foil between an outer window frame and an inner window frame of an electron beam permeable window, coating this with aluminium and titanium by converting aluminium and titanium to a metallic vapor state and subjecting this to thermal diffusion treatment.
