Moreover, when the keyboard is assembled on the casing, the ground terminals will contact the metal domes or the metal foils, so that the keyboard can be grounded through the metal domes or the metal foils.

However, since the metal dome not only has high production cost, but also takes time to assemble, the use of the metal dome will increase the production cost of the notebook computer. In addition, since the shell itself is not elastic, attaching the metal foils is likely to cause poor contact between the ground terminals and the metal foils.

The conductive material layer 230 is, for example, conductive tape, conductive paint or other conductive materials, which covers part of the carrier 220 and corresponds to a ground terminal (not shown in FIG. 2 ) at the bottom of the keyboard 100 . When the keyboard 100 is assembled with the casing 200 , the frame 210 surrounds the keyboard 100 , the carrier board 220 carries the keyboard 100 , and the ground terminal contacts the conductive material layer 230 . At this time, the keyboard 100 can be grounded through the conductive material layer 230 . Wherein, the frame 210 and the carrier 220 are, for example, formed integrally, and they are, for example, injection-molded plastic products. The structure of the carrier 220 and the connections among the keyboard 100 , the carrier 220 and the conductive material layer 230 will be described in more detail below.

Referring to FIG. 2 and FIG. 3 , the carrier board 220 may include a supporting portion 240 surrounding the opening 222 and an elastic portion 250 a connected to the supporting portion 240 . In the first embodiment, the carrier board 220 has, for example, two gaps 224, and these gaps 224 are formed on opposite sides of the elastic portion 250a, for example. Moreover, the gaps 224 extend from the opening 222 toward the frame 210 , for example. Moreover, the elastic portion 250 a has a first surface 252 facing the keyboard 100 , a second surface 254 opposite to the first surface 252 , and a protruding portion 256 a formed on the first surface 252 .
