Title:
MAGNETIC SENSOR
Document Type and Number:
WIPO Patent Application WO/2012/137544
Kind Code:
A1
Abstract:
A plurality of magnetic resistance element mounting sections (13i, 13j, 13k) etc., are formed on the top section of a case (1). Magnet holding sections (14) that house a plurality of magnets (5) are formed in the bottom section of the case (1) and each of the magnets (5) are housed in these magnet holding sections (14). Part of the lower surface of a magnetic resistance element (2j) is joined by an adhesive layer (7) to the magnetic resistance element mounting section (13j) corresponding to the position at a section facing the magnet (5) and the magnet (5). Nearly the entire lower surface of magnetic resistance elements (2i, 2k) are joined by the adhesive layer (7) to the magnetic resistance element mounting sections (13i, 13k) etc., not corresponding to the position at a section facing the magnet (5) and the magnet (5). As a result, a magnetic sensor is configured that is unlikely to generate piezoelectric noise even if the amplitude of bending vibration caused by sympathetic vibration in conjunction with the lengthening of the magnetic sensor increases.
