1. A liquid leakage detector comprising:
at least two conductors comprising a first conductor and a second conductor,
wherein the first conductor and the second conductor are configured to be electrically connected to each other through a liquid, and
wherein the first conductor and the second conductor are each directly covered by a braid comprising basalt fibers to respectively form a first electrode wire and a second electrode wire,
the liquid leakage detector further comprising a support material supporting the first electrode wire and the second electrode wire,
wherein the first electrode wire and the second electrode wire are supported by the support material so as to be disposed in parallel with each other with a clearance therebetween,
wherein the support material is formed into a net shape by braiding a water-repellant resin yarn, and
wherein the resin yarn has a pitch of 5 mm to 20 mm.
