In which a conductive layer may be provided in an appropriate form as needed, for example, the body 10 includes at least two of a first conductive layer 12 formed as a low resistance conductive sheet, a second conductive layer 13 formed as a conductive surface, and a third conductive layer formed by providing conductive particles 111 on the adhesive layer 11.

In the embodiment shown in fig. 1 to 3, the conductive double-sided tape includes a first conductive layer 12 formed as a low-resistance conductive copper sheet, a second conductive layer 13 formed as a copper conductive surface, and a third conductive layer formed by disposing conductive particles 111 on the adhesive layer 11. The first conductive layer 12, the second conductive layer 13 and the third conductive layer can effectively improve the conductivity of the conductive double-sided tape to meet the required electrical connection.

In addition, in order to ensure continuous and effective bonding while achieving bonding fixation, the main body 10 includes a buffer structure, and two bonding layers 11 are disposed on both sides of the buffer structure in the thickness direction of the main body. Thus, when the adhesive layer 11 on one side is used for bonding, the buffer structure can buffer the force applied to the other side to protect the adhesive layer 11 for bonding, thereby prolonging the service life of the bonding surface of the adhesive layer 11.

Wherein, the buffer structure can be adaptively arranged according to the form and the position of the conductive layer. For example, the main body 10 includes the first conductive layer 12, and the buffer structure includes buffer layers 14 stacked on both sides of the first conductive layer 12. Specifically, the buffer layers 14 formed of a buffer material may be provided on the upper and lower sides of the first conductive layer 12, respectively, or a cavity may be formed in the buffer layer 14 formed of a buffer material and the first conductive layer 12 may be placed in the cavity. In addition, the buffer structure may include buffer air bags 15 disposed on both sides of the first conductive layer 12 in the width direction, and may also perform a buffer function.

Wherein the second conductive layer 13 may be positioned in a suitable manner, i.e. fixed with respect to the buffer structure, e.g. fixed to the bottom of the buffer layer 14 in fig. 1. To facilitate heat dissipation from the second conductive layer 13, the body 10 includes a heat dissipation layer 16 formed adjacent to the second conductive layer 13, wherein the heat dissipation layer 16 may also be positioned in a suitable manner to be fixed relative to the second conductive layer 13, such as to the bottom of the second conductive layer 13 in fig. 1.

In addition, a release paper 30 is provided outside the adhesive layer 11 in order to protect the adhesive surface of the adhesive layer 11 when not in use. The release paper 30 may extend from the body 10 to cover the tab 20 to provide protection to the tab 20 as well. In addition, an insulating layer 40 may be disposed on the outer side of the release paper 30 to provide insulation protection for the conductive double-sided tape. Wherein the insulating layer 40 may completely cover the release paper 30, i.e., extend from the main body 10 to cover the tab 20, thereby providing protection to the tab 20.
