An embodiment relates to a heat transfer device including a heat generating device configured to generate heat having predetermined intensity by a user, a cover in contact with a body of the user while covering the heat generating device, and a heat transfer medium provided between the heat generating device and the cover to transfer the heat generated by the heat generating device, wherein the heat transfer medium is a structure that is formed by entangling a single wire having a predetermined length and has a predetermined width and a predetermined height, and is a structure that is compressed in an axial direction when being in contact with the body of the user and thus has a Poisson's ratio of 0.5 or higher. Thus, a structural change in the heat generating device is not required and only a material in contact with the heat generating device is changed, so that generated heat may more rapidly reach the body of the user.
