PROBLEM TO BE SOLVED: To provide a liquid level detector that firmly supports a holder with respect to a frame in a rotatable manner.SOLUTION: A liquid level detector includes: a holder 2 for rotating a circuit board in association with movement of a float that moves, following a liquid level; terminals each including an elastic piece having a contact portion to be in contact with an electrode part of the circuit board 4; and a frame 1 with part of the terminals embedded therein. The frame 1 includes a bearing part 14, at the outer periphery of the frame, for supporting an end of a float arm 3 held by the holder 2 in a rotatable manner. The holder 2 includes a holding part 2B having an upper piece 2A and a lower piece 2B2 with the bearing part 14 disposed therebetween. The frame 1 also includes a first guide part where the lower piece 2B2 of the holding part 2B of the holder 2 can move in a rotation axis S direction of the holder 2 and a second guide part 18 where the lower piece 2B2 of the holding part 2B can move in a direction perpendicular to the rotation axis S direction of the holder 2. |
