That is, the lighting state of the lighting part adjacent to the lighting part group 72 can be clearly distinguished, and the user is prevented from misidentifying the lighting state of the lighting part group 72. Further, since the shadow of each boundary wall 74 of the boundary wall 74 is applied to the lighting unit group 72 by sunlight, indoor lighting, etc., the visibility is further improved. Therefore, it is possible to obtain the communication device 1 that allows the user to clearly visually recognize the lighting location without increasing the number of components.

The surface of each of the first lighting part 72A, the second lighting part 72B, the third lighting part 72C, and the fourth lighting part 72D has been subjected to matte texture processing, and a plurality of minute protrusions are formed. Have. Therefore, the diffusibility of the light emitted from the lighting unit group 72 can be improved, and the visibility is further improved. Moreover, since the surface of the lighting unit group 72 is not glossy by applying the matte texture, sunlight, indoor lighting or the like is reflected on the surface of the lighting unit group 72 and the light emitted from the light emitting unit group 42 is reflected. It is possible to prevent the visibility from deteriorating. Further, since the matte texture is applied to the surface of the lighting unit group 72, the number of parts is increased, but the inexpensive communication device 1 can be obtained.

In this embodiment, the communication device 1 is detachably attached to the storage unit 103 of the air conditioner 100, and is covered by closing the front panel 101. Therefore, by opening the front panel 101 of the air conditioner 100 and taking out the communication device 1, it is possible to check the setting of the communication device 1, the communication state, and the like. On the other hand, by closing the front panel 101 in a state in which the communication device 1 is attached to the storage unit 103 of the air conditioner 100, the indicator lamp group 12 is covered with members constituting the air conditioner 100. As a result, it is possible to suppress the light emitted from the display lamp group 12 of the communication device 1 from directly entering the eyes of the user, and to obtain the air conditioner 100 in which the display of the display lamp group 12 is not obstructive.
