What is claimed is: 1. A pressure sensor comprising a sealed pressure transmission fluid, wherein the case facing the diaphragm is formed with an enlarged portion connected to a pressure guiding passage. (2) A pressure sensor comprising a diaphragm provided in a case, a pressure detection section provided on a pedestal within the case to detect pressure, and a pressure transmission fluid sealed between the pressure detection section and the diaphragm. The pressure sensor is characterized in that the pedestal has a diameter larger than that of the pressure sensing section and is penetrated by a terminal of an output line that guides an electrical signal from the pressure sensing section to the outside.
