The base includes a first base portion configured to define first inlet and outlet regions for the first and second air flows; and a second base portion configured to define second inlet and outlet regions in communication with the first inlet and outlet regions. The first and second inlet regions form at least a part of the inlet channel. The first and second outlet regions form at least a part of the outlet channel. ## Claims ### Claim 1 A dehumidifying device, comprising: a base configured to define an inlet channel, through which first air flows, and an outlet channel, through which second air less humid than the first air flows; and a first dehumidifier including a first inlet in communication with the inlet channel and a first outlet in communication with the outlet channel, the first dehumidifier dehumidifying the first air between the first inlet and the first outlet to generate the second air, wherein each of the inlet and outlet channels is formed by continuously and linearly aligned through-holes, and wherein the base includes a first base portion configured to define a first inlet region including one of the through-holes of the inlet channel, through which the first air flows, and a first outlet region including one of the through-holes of the outlet channel, through which the second air flows; and wherein the base also includes a second base portion configured to define a second inlet region including the other of the through-holes of the inlet channel in communication with the first inlet region and a second outlet region including the other of the through-holes of the outlet channel in communication with the first outlet region. ### Claim 2 (depends on 1) The dehumidifying device according to claim 1, further comprising: a second dehumidifier including a second inlet in communication with the inlet channel and a second outlet in communication with the outlet channel, the second dehumidifier dehumidifying the first air between the second inlet and the second outlet to generate the second air, wherein the first dehumidifier is attached to the first base portion, and wherein the second dehumidifier is attached to the second base portion. ### Claim 3 (depends on 1) The dehumidifying device according to claim 1, wherein the first base portion defines a first opening as a first end of the first inlet region and a second opening as a second end of the first outlet region, the second end being opposite to the first end; wherein the second base portion defines a third opening as a third end of the second inlet region and a fourth opening as a fourth end of the second outlet region, the fourth end being opposite to the third end; and wherein the first base portion is adjacent to the second base portion so that the first opening communicates with the third opening and the second opening communicates with the fourth opening. ### Claim 4 (depends on 1) The dehumidifying device according to claim 1, wherein the first dehumidifier extends along an imaginary plane intersecting with the inlet and outlet channels. ### Claim 5 (depends on 1) The dehumidifying device according to claim 1, wherein the first base portion is fastened to the second base portion by a fastening member extending through the first and second base portions. ### Claim 6 (depends on 1) The dehumidifying device according to claim 1, further comprising: a separator configured to separate moisture from the first air; and a check valve which allows passage of the second air in a first direction from the first inlet to the first outlet and blocks the second air from passing in a second direction opposite to the first direction, wherein the first base portion defines an opening to which the separator is connected, wherein the second base portion defines an opening to which the check valve is connected. ### Claim 7 (depends on 6) The dehumidifying device according to claim 6, wherein the base includes a third base portion situated between the first and second base portions, and wherein the third base portion defines the inlet and outlet channels in cooperation with the first and second base portions. ### Claim 8 A dehumidifying module connected to another base portion which defines channels through which air flows, comprising: a base portion configured to define an inlet region including a through hole, through which first air flows, and an outlet region including a through hole, through which second air less humid than the first air flows; and a first dehumidifier including a first inlet in communication with the inlet region and a first outlet in communication with the outlet region, the first dehumidifier dehumidifying the first air between the first inlet and the first outlet to generate the second air, wherein the inlet region communicates with one of the channels to partially define an inlet channel, through which the first air flows, and the outlet region communicates with another of the channels to define an outlet channel, through which the second air flows, when the base portion is connected to the other base portion, wherein the inlet region is continuously and linearly connected to a through hole formed in the other base portion, and wherein the outlet region is continuously and linearly connected to another through hole formed in the other base portion.
