Abstract
A sealant film used by being laminated on a substrate includes a sealing layer including a first polyolefin resin and an antifogging agent and a first resin layer including 10% to 40% by mass of a cyclic polyolefin resin and 60% to 90% by mass of a second polyolefin resin, wherein the second polyolefin resin is not a cyclic polyolefin resin. The first resin layer is disposed on a surface of the sealing layer, and has a phase-separated structure in which the cyclic polyolefin resin is dispersed in the form of a layer in the second polyolefin resin.
