1. A method for manufacturing a member,
the member comprising:
a first member made of a metal, wherein the first member comprises a base material of which at least a surface is made of a material containing Al as a main component, and an irregular part formed as irregularities on the surface of the base material, the irregular part being made of the material used for the surface of the base material, wherein the first member is a housing part of a battery pack; and
an adhesive layer formed on a surface of the irregular part, the adhesive layer comprising an adhesive formed therein, the adhesive having an isocyanate group for bonding the first member with a second member, wherein the second member is a plate material containing Fe that covers the housing part of the battery pack,
the method including:
forming the irregular part on the surface of the base material;
applying the adhesive to the surface of the irregular part;
disposing the second member on the adhesive that has been applied to the surface of the irregular part; and
after disposing the second member on the adhesive that has been applied to the surface of the irregular part, bonding the surface of the irregular part with the adhesive applied to the surface of the irregular part by drying the adhesive, and thereby forming the adhesive layer.
