PROBLEM TO BE SOLVED: To comprise cable alignment by which signal transmission on cable does not come under an influence.SOLUTION: A communication device 300 includes: a circuit board 100; an enclosure 301 into which the circuit board 100 is inserted, and the aeration direction of which is a direction in which air flowing in from a front plate 304 is discharged to the outside from a rear plate 303 facing the front plate 304 via the circuit board 100 and is a direction in which the circuit board 100 is inserted or pulled out; a connection plate 302 that includes a vent hole 321 communicating between a first space at the front plate 304 side and a second space at the rear plate 303 side and is connected with the circuit board 100 at a front surface 302a facing the front plate 304; and a cable 400 that connects with the circuit board 100 such that the circuit boards can communicate with each other at a rear surface 302b of the connection plate 302 facing the rear plate 303, and is pulled around in a fourth space which is the second space excluding a third space, which is an area where the vent hole 321 is projected in the aeration direction relative to the rear plate 303. |
