Title:
DYNAMIC QUANTITY SENSOR
Document Type and Number:
Japanese Patent JP2014202562
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide dynamic quantity sensor capable of suppressing the entry of noise to a conductive member electrically connecting a sensor portion and a circuit portion.SOLUTION: Of a case 30, on a wall surface of a recessed portion 31, a conductor pattern 38 is formed. An external terminal 35b electrically connected to the external ground is formed on an outer wall surface of the case 30, and inner wiring 37b for electrically connecting the conductor pattern 38 and the external terminal 35b is formed between an inner wall surface and the outer wall surface of the case 30. Therefore, noise is easy to enter the conductor pattern 38 connected to the external ground, and the entry of noise to the conductor member can be suppressed. Consequently, the generation of a detection error due to noise can be suppressed.
