The underlayer may contain two or more kinds of Group 4 elements.

[0285] The Group 5 elements of the periodic table (hereinafter also referred to as "Group 5 elements") refer to vanadium, niobium, and tantalum.

The underlayer may contain two or more types of Group 13 elements.

[0287] Group 15 elements of the periodic table (hereinafter also referred to as "Group 15 elements") refer to nitrogen, phosphorus, arsenic, antimony, and bismuth. As the Group 15 elements, from the viewpoint of forming a surface treatment layer on the underlayer more uniformly without defects, or from the viewpoint of further suppressing the variation in the composition of the underlayer between samples, phosphorus, antimony, and bismuth are preferable, and phosphorus and bismuth are more preferable. The underlayer may contain two or more types of Group 15 elements.

[0288] As the specific element contained in the underlayer, Group 1 elements, Group 2 elements, and Group 13 elements are preferred because they provide a surface treatment layer with superior abrasion resistance, Group 1 elements and Group 2 elements are more preferred, and Group 1 elements are even more preferred. The specific element may be one type of element or two or more types of elements.

The thickness of the underlayer is preferably 1 to 100 nm, more preferably 1 to 50 nm, and even more preferably 2 to 20 nm. If the thickness of the underlayer is equal to or greater than the lower limit, the adhesion of the underlayer to the surface treatment layer is improved, and the surface treatment layer has better abrasion resistance. If the thickness of the underlayer is equal to or less than the upper limit, the underlayer itself has better abrasion resistance. The thickness of the underlayer is measured by observing a cross section of the underlayer with a transmission electron microscope (TEM).

The granulated body refers to a solid obtained by kneading the powder of the deposition material with a liquid medium (e.g., water, organic solvent) to obtain particles, and then drying the particles.

[0294] The deposition material can be produced, for example, by the following method. A method of obtaining a powder of deposition material by mixing silicon oxide powder with a powder of an oxide of a specific element. A method in which the above-mentioned deposition material powder and water are kneaded to obtain particles, and then the particles are dried to obtain granules of the deposition material. A method of mixing a powder containing silicon (e.g., powder made of silicon oxide, silica sand, silica gel), a powder containing a specific element (e.g., powder of an oxide of a specific element, carbonate, sulfate, nitrate, oxalate, hydroxide), and water, drying the mixture, and then firing the dried mixture or a compact obtained by pressing the mixture to obtain a sintered body. A method in which a powder containing silicon (e.g., powder made of silicon oxide, silica sand, silica gel) and a powder containing a specific element (e.g., powder of an oxide, carbonate, sulfate, nitrate, oxalate, hydroxide of a specific element) are melted at high temperature, and the melt is then cooled and solidified to obtain a molten material.

[0295] A specific example of a deposition method using a deposition material is a vacuum deposition method, in which a deposition material is evaporated in a vacuum chamber and attached to the surface of a substrate.

The electron gun method is preferred as the evaporation method of the deposition material because it can evaporate high melting point substances because it can heat locally, and because the areas not hit by the electron beam are at low temperature, there is no risk of reaction with the container or contamination with impurities. The evaporation method of the deposition materials may use multiple boats, or may use a single boat containing all the deposition materials. The deposition method may be co-deposition or alternating deposition. Specifically, examples include a case where silica and a specific source are mixed in the same boat and used, a case where silica and a specific element source are placed in separate boats and co-deposited, and a case where they are placed in separate boats and alternately deposited.
