Abstract: Provided are a gas separation membrane which has a resin layer containing a compound having a siloxane bond, in which the resin layer containing a compound having a siloxane bond satisfies Expressions 1 and 2, and at least one of gas permeability or gas separation selectivity is high under high pressure; a method of producing a gas separation membrane; a gas separation membrane module; and a gas separator. 0.9≥A/B≥0.63 Expression 1 B≥1.7 Expression 2 In the expressions, A represents an O/Si ratio that is a ratio of the number of oxygen atoms relative to the number of silicon atoms contained in the resin layer containing a compound having a siloxane bond at a depth of 10 nm from the surface of the resin layer containing a compound having a siloxane bond, and B represents an O/Si ratio that is a ratio of the number of oxygen atoms relative to the number of silicon atoms in the surface of the resin layer containing a compound having a siloxane bond.

Abstract: Provided are a physical property measurement method, a physical property measurement device, and a probe that can simply measure physical properties of a surface layer portion of an object. A physical property measurement method includes a step of bringing a probe into contact with a surface layer portion of a liquid or gel-like object and maintaining a contact state, a step of measuring a height of the object rising along the probe in contact with the object, and a step of calculating viscous properties or elastic properties of the surface layer portion of the object using the measured height of the object rising along the probe.
