Abstract:
A sealing sheet is configured to restrain at least one of leakage of liquid in and out. The sealing sheet includes: a film member which is impermeable to the liquid and configured to cover a region that needs to be sealed; and electrical wires which are arranged on the film member. An electrical signal corresponding to change in electrical resistance due to contact with the liquid is obtainable from the electrical wires.
