A secondary battery includes an outer package member, a battery device, and an adhesive member. The outer package member has flexibility. The battery device is contained inside the outer package member, and includes a positive electrode and a negative electrode. The positive electrode and the negative electrode are opposed to each other and are wound. The adhesive member is disposed between the outer package member and the battery device. The adhesive member is adhered to each of the outer package member and the battery device. The positive electrode and the negative electrode are wound in such a manner that the positive electrode or the negative electrode is disposed in an outermost wind. The adhesive member includes a non-heat adhesive layer and a heat adhesive layer. The non-heat adhesive layer is adhered to the outer package member. The heat adhesive layer is adhered to the battery device and includes oriented polystyrene.
