LIQUID DISCHARGE STRUCTURE

An objective of the present invention is to improve the discharge capacity for liquid collected within a casing while suppressing liquid entering a discharge opening from the outside. A liquid discharge structure 10 includes a plate-shaped bottom wall 11 with a discharge opening 111 for liquid, the liquid being collected inside a casing 1 which is configured to be installed in a vehicle, a blocking wall 12 outside the bottom wall 11, wherein the blocking wall 12 is overlapped with the discharge opening 111 in a plan view on the bottom wall 11 and opposed to the bottom wall 11 with a gap between the blocking wall 12 and the bottom wall 11, and a fixing mechanism 13 which is disposed not to be overlapped with the discharge opening 111 in the plan view, wherein the fixing mechanism 13 is configured to fix the blocking wall 12 relative to the bottom wall 11 in an attachable and detachable manner.
