1. A window comprising:
a window frame having an opening defined through which an outdoor space and an indoor space communicate;
a pair of sashes disposed in the window frame along an opening direction and a closing direction opposite to the opening direction;
variable transmittance windowpanes configured to be fitted in the pair of sashes to open and close the opening together with the pair of sashes, the variable transmittance windowpanes having a transmittance variable by electrical connection;
first conductive members disposed on the pair of sashes and electrically connected with the variable transmittance windowpanes to supply electric power to the variable transmittance windowpanes; and
a second conductive member electrically connected with the first conductive members to supply the electric power to the first conductive members from outside the window frame,
wherein each of the first conductive members is connected to at least part of a first surface that is a surface facing the window frame among surfaces of the corresponding sash,
wherein the second conductive member is connected to at least part of a second surface that is a surface facing the first surface, among surfaces of the window frame,
wherein the sash is configured to close the opening together with the corresponding variable transmittance windowpane is in a closed position,
wherein the first surface and the second surface are spaced apart from each other by a predetermined distance,
wherein the first conductive member includes a first protruding member obliquely protruding from the first surface toward the second surface, and
wherein the second conductive member includes a second protruding member obliquely protruding from the second surface toward the first surface, the second protruding member being brought into contact with the first protruding member to electrically connect the first conductive member and the second conductive member when the sash is located in the closed position.
