<p>The present invention provides a pressure detection device which enables a simplified structure and reduced manufacturing costs. A pressure detection device is characterized by being provided with: a fluid inflow member (10); a semiconductor-type pressure sensor (20) (sensor); a first unit member (30) which has a first lead terminal (33) connected to the sensor (20); a second unit member (50) which has a lid member (40) that covers the sensor (20) and forms an enclosed space, and a second lead terminal (51) that is connected to the first lead terminal (33); and a resinous cover member (60) which combines the respective members (10, 20, 30, 40, 50) and covers the members (30, 40, 50) by resin molding with part of the second lead terminal (51) exposed to the outside therethrough, and characterized in that the sensor (20) and the first lead terminal (33) are connected by wire bonding, the first lead terminal (33) and the second lead terminal (51) are joined by welding, and the joined portion is covered when the resinous cover member (60) is molded.</p> |
