A heat exchanger includes a fin, the fin including a metal base and a porous anodized layer formed on the metal base. A surface of the porous anodized layer has a submicron-order uneven structure, the uneven structure including a plurality of recessed portions whose two-dimensional size viewed in a normal direction of the surface is more than 100 nm and less than 500 nm.

Heat exchanger including fins with surface having bactericidal activity, metallic member with surface having bactericidal activity, method for inhibiting mold growth and sterilization method both using surface of fins of heat exchanger or surface of metallic member, and electrical water boiler, beverage supplier, and lunch box lid all including metallic member

A food preserving method is a method for preserving food using a food film (A), (B). The food film (A), (B) has a surface which has a plurality of raised portions (Ap), (Bp). The two-dimensional size of the plurality of raised portions (Ap), (Bp) is in a range of more than 20 nm and less than 500 nm when viewed in a direction normal to the food film (A), (B). The method includes bringing the food into direct contact with the surface.
