PROBLEM TO BE SOLVED: To provide a magnetometric sensor suppressing penetration of a liquid into a holder. SOLUTION: This magnetometric sensor used for position detection of a pneumatic device 30 is provided with: a sensor circuit part 11 for detecting magnetism; a lead wire 12 connected to the sensor circuit part 11; a holder 13 storing the sensor circuit part 11, and having a hole part 13c for taking out the lead wire 12 to the outside; and a boot 14 having an opening part 14a into which the holder 13 is inserted, and formed in a bag shape covering the holder 13. In the boot 14, a though hole 14b through which the lead wire 12 penetrates is formed. The boot 14, as formed of a rubber material, adheres to the holder 13 near the opening part 14a, and also adheres to the lead wire 12 on the inner circumferential surface of the though hole 14b. The boot 14 further adheres to the holder 13 by an adhesive 18 near the opening part 14a. COPYRIGHT: (C)2011,JPO&INPIT |
