摘要： Provided is a pellicle frame that can prevent generation of haze and reduces a surface glittering defect under irradiation with collectedlight, and a method of manufacturing the same. Thepellicle frame is obtained by using an aluminum frame material having a structure satisfying predetermined conditions on the circle-equivalent diameters of a Mg 2 Si crystallized product, an Al 2 CuMg crystallized product, an Al-Fe-based crystallized product (Al m Fe or Al 7 Cu 2 Fe), and an Al 2 CuMg crystallized product and on the area ratios of those crystallized products each having a circle-equivalent diameter of 1 µm or more, and in addition, subjecting the aluminum frame material to anodic oxidation processing using an alkaline electrolytic solution containing as an electrolyte a predetermined organic acid salt. In addition, the method of manufacturing a pellicle frame includes: preparing an aluminum frame material having a structure as described above; and subjecting the aluminum frame material to anodic oxidation processing using an alkaline electrolytic solution containing a predetermined organic acid salt, to form an anodic oxide film.

摘要： With regard to carrying out friction stir welding on a composite body having a first surface and a second surface different from the first surface, the present invention carries out friction stir welding of the second surface while suppressing influence of deformation occurring in the composite body due to the friction stir welding of the first surface. The present invention comprises: an arrangement step for assembling each metal member (11, 12, 13) in an arranged relationship to form a composite body (25); a securing step for securing the composite body (25) in a state in which the metal members (11, 12, 13) are assembled together; a first friction stirring step for carrying out friction stir welding of the secured composite body (25) by inserting a stirring pin (51) from a first surface (26); a rotating step for rotating the secured composite body (25) so as to achieve a positional relationship in which a second surface (27) opposes a rotary tool (50); and a second friction stirring step for carrying out friction stir welding of the secured composite body (25) by inserting the stirring pin (51) from the second surface (27).
