PROBLEM TO BE SOLVED: To provide a liquid level detection device preventing electrolytic corrosion by maintaining a fixing state between a wall part and a lid part. SOLUTION: A plurality of terminals having different potentials are exposed from a covering part. The exposed parts are arranged side by side, and the circumference of the plurality of exposed parts is covered by a tube part. The tube part includes: three or more wall parts fixed to the covering part and arranged at the prescribed interval so as to be disposed opposite each other via one exposed part; and two lid parts disposed opposite each other so as to integrally hold the entire wall parts therebetween. The hollow in the tube part is partitioned into a plurality of regions by the wall parts and the lid parts, wherein one exposed part is disposed in each of the partitioned region. A female engagement part is formed in each of two wall parts. A male engagement part is formed in each of two lid parts. A stopper preventing disengagement between the female engagement part and the male engagement part formed in the other lid part is formed in one of the two lid parts. COPYRIGHT: (C)2011,JPO&INPIT
