Pressure sensor and manufacturing method of said sensor

摘要

A pressure sensor is provided with the cap (17) on a measuring portion of a diaphragm (11) to which a first end (15A) of a flexible board (15) is connected while a second end (15B) of the flexible board (15) is connected to a circuit board spaced apart from the diaphragm (11). The flexible board (15) is provided with the first end (15A), a belt portion (15C) that is bent at an angle of ninety degrees or more relative to the first end (15A) in a direction to be away from the circuit board and is curved along the outer circumference of the diaphragm (11), and the second end (15$) that is bent at an angle of nicety degrees or more relative to the belt portion (15C) to be connected to the circuit board.
