Problem to be solved: to provide an enclosure and an electrode structure in which an electric field is efficiently applied to an object (especially fresh food), and the freshness of the object can be kept longer.The container 1 has a container body 2 having a storage chamber 20 for accommodating the object x, an electrode 5 for forming an electric field in the chamber 20, a support 6 fixed to the container main body 2 and supporting the electrode 5 in the chamber 20.The support part 6 has fixed portions 61 and 62 fixed to the container body 2, a projecting portion 63 projecting from the fixing portions 61 and 62 toward the receiving chamber 20 and having an electrode 5 arranged therein, and a distance d1 between the projection 63 and the container body 2 is fixed to the fixing part 61, The distance 62 is larger than the distance d2 of the container body 2.Diagram
