The second side 121T intersects the first side 121S. The third side 121U faces the first side 121S and intersects the second side 121T. The fourth side 121V intersects the first side 121S and the third side 121U and faces the second side 121T. A rectangular shape is formed by the first to fourth sides 121S, 121T, 121U and the side 121V.

The water collecting part 150Q protrudes from the surface 121P facing the electronic component in the lid member 120P. The water collecting portion 150Q is formed in a portion corresponding to the first side 121S. The water collecting portion 150Q swells along the surface direction of the facing surface 121P to the side opposite to the predetermined region 121F corresponding to the region of the electronic component. In FIG. 1, the water collecting portion 150Q is disposed at the center X0 of the first side 121S. However, the embodiment of the present invention is not limited to this.
The facing surface 121P is gradually inclined downward as the facing surface 121P faces upward, with increasing distance from the center X0 side of the first side 121S. Furthermore, the opposing surface 121P has the opposing surface 121P facing upward, and the first side 121S side is closer to the third side 121U than the second side 121T side and the fourth side 121V side. Is also located below.
That is, the lid member 120P is a member for an electronic device having a lid that covers the first surface of the electronic component. The lid member 120P includes a facing surface 121P and a water collecting part 150Q. The facing surface 121P has a predetermined region 121F that faces the second surface of the electronic component opposite to the first surface of the electronic component.

It has a fourth side 121V that intersects the first side 121S and the third side 121U and faces the second side 121T. The opposing surface 121P has a rectangular shape defined by the first to fourth sides 121S, 121T, 121U, 121V. The water collecting portion 150Q protrudes from the facing surface 121P, is provided in the vicinity of the first side 121S, and is away from the predetermined area 121F (a direction perpendicular to the first side 121S and from the third side 121U). One side 121S) and bulges (protrudes) in the outer direction, which is the direction along the opposing surface 121P. With the facing surface 121P facing upward, the facing surface 121P is gradually inclined downward as the distance from the center X0 of the first side 121S increases. With the facing surface 121P facing upward, in the vicinity of the second and fourth sides 121T and 121V, the portion of the facing surface 121P on the first side 121S side is the facing surface 121P on the third side 121U side. It is located below the part.

In the lid member 120P of the electronic device configured as described above, the opposing surface 121P is separated from the center X0 side of the first side 121S in a state where the electronic device is disposed with the opposing surface 121P facing upward. Therefore, it is gradually inclined downward. Therefore, in the unlikely event that liquid enters the predetermined region 121F, in this state, the liquid is guided away from the center X0 side of the first side 121S. Further, on the second side 121T side and the fourth side 121V side, the first side 121S side is positioned below the third side 121U side. Therefore, the liquid is guided to the first side 121S side on the second side 121T side and the fourth side 121V side. In this way, the liquid can be guided to the edge side of the predetermined region 121F and away from the electronic component. For example, when the water collection part 150Q is arrange | positioned at the edge part side of the 1st edge | side 121S, the induced | guided | derived liquid can be collected by the water collection part 150Q.
In a state in which the electronic device is arranged with the facing surface 121P facing downward, the facing surface 121P gradually tilts upward as the distance from the center X0 side of the first side 121S increases, that is, the first side 121S. As it approaches the center X0 side, it gradually inclines downward. Therefore, the liquid is guided to the center X0 side of the first side 121S, and the liquid can be guided to the edge side of the predetermined region and away from the electronic component. For example, when the water collecting part 150Q is disposed on the center X0 side of the first side 121S, the induced liquid can be collected in the water collecting part 150Q. Further, on the second side 121T side and the fourth side 121V side, the third side 121U side is positioned below the first side 121S side. Therefore, the liquid is guided to the third side 121U side on the second side 121T side and the fourth side 121V side. In this way, the liquid can be guided to the edge side of the predetermined area and away from the electronic component.
