The water- and oil-repellent agent composition contains a fluorine-containing polymer having a unit based on a monomer (a), a unit based on a monomer (b1), a unit based on a monomer (b2), a unit based on a monomer (b3), and a unit based on a monomer (c), wherein relative to all the units that constitute the fluorine-containing polymer, the proportion of the unit based on the monomer (a) is from 70 to 80% by mass, the proportion of the combination of the unit based on the monomer (b1), the unit based on the monomer (b2) and the unit based on the monomer (b3) is from 12 to 28% by mass, and the proportion of the unit based on the monomer (c) is from 2 to 8% by mass. Monomer (a): a compound represented by (Z-Q)nX. Monomer (b1): a monomer not having a polyfluoroalkyl group (Rf group), but having an alkyl group of 22 carbon atoms. Monomer (b2): a monomer not having an Rf group, but having an alkyl group of 20 carbon atoms. Monomer (b3): a monomer not having an Rf group, but having an alkyl group of 18 carbon atoms. Monomer (c): a halogenated olefin.

摘要： A carrier substrate to be used, when manufacturing a member for an electronic device on a surface of a substrate, by being bonded to the substrate, includes at least a first glass substrate. The first glass substrate has a compaction described below of 80 ppm or less. Compaction is a shrinkage in a case of subjecting the first glass substrate to a temperature raising from a room temperature at 100° C./hour and to a heat treatment at 600° C. for 80 minutes, and then to a cooling to the room temperature at 100° C./hour.

摘要： A method of producing a glass article includes holding a carrier having a circular shape, in which a glass substrate having a circular shape is retained, with an upper surface plate and a lower surface plate; and polishing the glass substrate by rotating the carrier with respect to the upper surface plate and the lower surface plate, to obtain the glass article. The glass substrate is disposed in the carrier such that, in a top plan view, a center of the carrier is included in a region of the glass substrate, and a center of the glass substrate is shifted from the center of the carrier.
