Abstract
[Problems] Objects include providing a cover film for testing which can be well fixed to a substrate having a groove and with which a material that constitutes an adhesive layer does not invade into the groove and a specimen can be easily stored in the groove, providing a testing member including the cover film for testing, and providing a method of manufacturing the cover film for testing.[Solution] The cover film for testing (1) comprises a base material (10), a hydrophilic coating layer (20) laminated on a surface of the base material (10), and an adhesive layer (30) partially laminated on a surface of the hydrophilic coating layer (20) opposite to the base material (10), whereby the cover film for testing (1) has a region in which the adhesive layer (30) is absent and the hydrophilic coating layer (20) is exposed.
