In Fig. 6, the water deflector 40 is inclined in the oblique direction D1 with respect to a horizontal plane P1. The support plate 31 of the keyboard module 30 is parallel to the horizontal plane P1.

Since the water deflector 40 is inclined with respect to the horizontal plane P1, the water droplets on the water deflector 40 can move or roll toward the drain groove 44 due to gravity. Further, since the water droplets are located between the water repellent layer 43 and the water repellent layer 34, it is possible to prevent the water droplets from adhering to the support plate 31 to help the water droplets flow between the support plate 31 and the water deflector 40.

Moreover, since the water guiding groove 42 is lower than the upper surface 46 of the body 41, the water droplets in the water guiding groove 42 are less likely to contact the support plate 31, so the water droplets in the water guiding groove 42 can move faster than the upper surface 46 of the body 41. The water droplets are fast. In other words, the water guiding groove 42 can accelerate the moving speed of the water droplets on the water guiding plate 40, and can also prevent the water droplets from flowing out from the side of the body 41 without the drainage groove 44.
