摘要

PROBLEM TO BE SOLVED: To shorten the time required for removing gas as the object of measurement from a gas transmission cell before measuring the gas permeability of a thin film material.SOLUTION: A gas permeability measuring device 30 includes: a transmission-side chamber 2 in which a gas permeable first support body 3 firmly fixed to the inner wall so as to cover at least part of a space 6 is provided and into which gas passing through a thin film material 50 flows; and a gas permeable second support body 4 which has a lower gas permeability than the first support body 3.SELECTED DRAWING: Figure 1
