Abstract
Provided is a test method performed using a lens which comes into contact with a human body during use, the test method including the steps of: providing a membrane member including a membrane swellable upon absorbing water and a supporting base having an annular shape to support an outer periphery of the membrane; allowing cells to adhere on the membrane of the membrane member; and bringing the membrane to which the cells are adhered into close contact with the surface of the lens, by immersing the membrane member and the lens into a liquid and deforming the membrane in a swollen state along the surface of the lens.
