Title:
MAGNETIC SENSOR
Document Type and Number:
WIPO Patent Application WO/2022/131060
Kind Code:
A1
Abstract:
The present invention addresses the problem of improving environment resistance. A magnetic sensor (10) comprises an insulated substrate (1), one or more magnetoresistive elements (2), a conductor (3), and a sealing member (4). The conductor (3) electrically connects the magnetoresistive element (2) with an external circuit. The sealing member (4) seals the entire magnetoresistive element (2) and at least a portion of each of the insulated substrate (1) and the conductor (3). The magnetoresistive element (2) has a magnetoresistive film (2a) and an electrode (2b). The magnetoresistive film (2a) is formed on a first surface (1A) of the insulated substrate (1). The electrode (2b) is provided to the first surface (1A) of the insulated substrate (1). One end (2aA) of the electrode (2b) is electrically connected to the magnetoresistive film (2a), and the other end (2aB) of the electrode (2b) is electrically connected to a first end part (3A) of the conductor (3). The sealing member (4) exposes a second surface (1B) of the insulated substrate (1) and a second end part (3B) of the conductor (3) from mutually different surfaces (1A, 1B).
