<p>Provided is an indicator whereby it becomes possible to prevent the adhesion of the indicator to a gas-permeable packaging material and it becomes also possible to achieve accurate detection even when a material of interest and the indicator are packed/sealed into the gas-permeable packaging material and a hydrogen peroxide sterilization treatment or a hydrogen peroxide plasma sterilization treatment is carried out using the packaging material. The indicator is a hydrogen peroxide sterilization or hydrogen peroxide plasma sterilization detection indicator, which comprises a base and a color-changing layer formed on the base, wherein the color of the color-changing layer is changed in the presence of hydrogen peroxide or hydrogen peroxide plasma, and wherein the indicator is characterized in that the color-changing layer has a surface roughness (Ra) of 2.5-15.0 µm.</p> |
