Abstract
[Object] Provided are a pressure detection unit and a pressure sensor using the same capable of performing a trimming operation using a simple structure during an assembly operation, and reducing a decrease in detection accuracy of a semiconductor type pressure detection device. [Solving Means] A pressure detection unit includes a base formed in a lid shape and made of ceramic, a receiving member formed in a plate shape, a diaphragm interposed between the base and the receiving member, a semiconductor type pressure detection device installed on a side of a pressure receiving space formed between the base and the diaphragm in the base, and three terminal pins electrically connected to the semiconductor type pressure detection device, the terminal pins penetrating the base, wherein the three terminal pins include an earth terminal pin, a power input terminal pin, and a signal output terminal pin.
