Document Type and Number:
WIPO Patent Application WO/2019/026623
Kind Code:
A1
Abstract:
In order to increase the noise resistance of a temperature detection element (T1) simply and at low cost, a circuit device (10), which is connected via an external signal line (20s) and an external signal ground line (20sg) to the temperature detection element (T1) for detecting the temperature of an object (2), comprises: an internal signal line (12s) that is connected to the external signal line (20s) via a connector (13); an internal signal ground line (12sg) that is connected to the external signal ground line (20sg) via the connector (13); a control circuit (11) that is connected to the internal signal line (12s) and the internal signal ground line (12sg), and detects the temperature of the object (2); a first high-frequency filter (B1) that is inserted into the foremost stage of the internal signal line (12s) as viewed from the connector (13); and a second high-frequency filter (B2) that is inserted into the foremost stage of the internal signal ground line (12sg) as viewed from the connector (13).
