Abstract
In a range detection device, a movable member has a magnetized portion and can move with a manual valve of a control device. A supporting member includes a plate portion having a surface opposed to the magnetized portion and a recess formed in an opposite surface of the plate portion, and supports the movable member such that the movable member is capable of moving parallel with the plate portion. A substrate is placed in the recess and has a first hole that penetrates the substrate. A magnetic detection element is installed to a surface of the substrate at a side of the plate portion to correspond to a position of the first hole, and detects magnetism of the magnetized portion. A sealing member is filled in the recess and covers the substrate and the magnetic detection element.
