## Abstract

Disclosed is an electronic device which includes an adhesive member interposed between a housing and a battery and including at least one adhesive layer in absence of a base or substrate, a first adhesive cover member interposed between the adhesive member and the battery, to surround a portion of the battery, such that the first adhesive cover member is detachably attached to the battery, and a second adhesive cover member spaced apart from the first adhesive cover member to surround another portion of the battery. Adhesive force of the adhesive member is stronger than adhesive force of at least one of the first adhesive cover member or the second adhesive cover member, and a partial area of the second adhesive cover member interposed between the battery and the adhesive member may have adhesive force stronger than adhesive force of a remaining area of the second adhesive cover member outside the partial area.
