Abstract: An object of the present disclosure is to provide coating film-attached glass having a glass substrate, and a coating film provided on at least a part of a surface of the glass substrate. The coating film-attached glass includes a modified layer in a region at a depth of 100 nm from the surface of the glass substrate on the coating film side in the depth direction. The modified layer has a microcrystalline structure at least in part. The coating film is a silicon-free and fluorine-containing diamond-like carbon film or an amorphous fluorine resin film. Another object of the present disclosure is to provide a production method for coating film-attached glass in which a coating film is formed on at least a part of a surface of a glass substrate.

Abstract: [Object] To provide a means manufacturing a medical vial which contains a Type IA borosilicate glass as the raw material and in which the elution amount of silica into a high ionic strength solution decreases to be equal to or less than the silica elution amount in a Type IB borosilicate glass.[Solution] A method for manufacturing a medical vial is a method for manufacturing a medical vial including a fire blast process of applying a flame ejected from a point burner to a deteriorated layer generated on the inner surface of a vial, in which the vial is molded from a glass tube containing a Type IA borosilicate glass as the raw material and the molar ratio of oxides contained in the borosilicate glass satisfies ψ=0.23±0.02 in ψ=[(Na2O+K2O)—Al2O3]/B2O3 and satisfies β=7.5±0.5 in β=B2O3/Al2O3.
