The anti-slip pad 100 may provide friction to the element 1 to be loaded. Accordingly, the anti-slip pad 100 can prevent the loaded device 1 from moving. In other words, since the anti-slip pad 100 provides friction to the element 1 to be loaded, the element 1 to be loaded is moved in the first and second directions (D1, D2) parallel to the upper surface of the anti-slip pad 100. ) Each may not slip. Accordingly, a collision between the elements to be loaded 1 or a collision between the elements to be loaded 1 and the frame 200 can be prevented, and the elements to be loaded 1 can be prevented from being damaged.

That is, while the load target element 1 is loaded and transported on the tray 1000, the anti-slip pad 100 can provide friction to the load target element 1 and prevent the load target element 1 from moving. You can do it. Accordingly, the anti-slip pad 100 can prevent the device 1 to be loaded from being damaged.

The anti-slip pad 100 may be disposed inside the frame 200. Additionally, when viewed from a plan view, each of the anti-slip pad 100 and the frame 200 may have a rectangular shape. For example, when viewed on the tray 1000 in a direction opposite to the normal direction (e.g., third direction D3) of the anti-slip pad 100, the anti-slip pad 100 and the frame 200 Each may have a rectangular shape. However, the present invention is not limited thereto. For example, when viewed from a plan view, the anti-slip pad 100 may have a rectangular shape with rounded corners.

In this case, the end of the element to be loaded (1) can be effectively engaged with the concave portion (22). In other words, when the first width W1 of the convex portion 21 exceeds approximately 5 mm or the second width W2 of the concave portion 22 exceeds approximately 5 mm, the loaded element 1 flows. It can be.

In one embodiment, with respect to the convex portion 21, the depressed depth H1 of the concave portion 22 may be greater than approximately 0.15 mm and approximately 0.25 mm. If the depressed depth H1 of the concave portion 22 is less than approximately 0.15 mm, the end of the element 1 to be loaded may not engage with the concave portion 22. In addition, since the thickness of the adhesive layer 20 (for example, the thickness t1 in FIG. 3) is approximately 0.3 mm or more and approximately 0.33 mm or less, the depressed depth H1 of the concave portion 22 is approximately 0.25 mm.
