Cover member and detection device equipped with cover member

Abstract

The present invention provides a cover member that can be easily manufactured without using mounting elements such as screws or adhesives, and that allows for the rapid and reliable attachment of a breathable membrane, as well as a detection device using the same. [Solution] A cover member is provided comprising a main body having an introduction section and a breathable membrane covering the introduction section, wherein the main body has a first opening and a first slit extending in a first direction from the first opening into the wall surface of the main body, and a second opening and a second slit extending in a second direction from the second opening into the wall surface of the main body, and the breathable membrane is a single strip-shaped body formed from a breathable and elastically deformable material, with one longitudinal end positioned in the first slit and the other longitudinal end positioned in the second slit.
