摘要:
A liquid leakage detector includes: a first liquid detection unit provided at a member to be detected, the first liquid detection unit being configured to detect a liquid leaked from the member to be detected; a liquid impermeable member which covers the first liquid detection unit to protect the same from the ambient air; and a determining unit configured to determine whether the liquid is leaking from the member to be detected in response to a signal from the first liquid detection unit.
