Abstract
Provided is a pressure detection unit in which a waterproof property can be improved. In a pressure sensor, a sealing-resin portion is joined to an outside side surface of an element main body made of stainless steel, aluminum, or nickel such that the sealing-resin portion surrounds a plurality of lead pins. In the pressure sensor, a roughened annular surface portion is provided at a region where the sealing-resin portion is joined on an upper end surface of the element main body so as to be disposed in a manner to partition an external peripheral edge and an internal peripheral edge arranged at the outside side surface of an element main body in the sealing-resin portion.
