In a pressure sensing device, a sensor housing container is provided with a flange-like mounting portion to be attached to a medium container made of a thin plate by a bolt. The flange-like mounting portion has a mounting plane of said sensor housing container and is formed to have a great thickness enough to provide high rigidity. At the mounting plane, there are provided an opening through which a nipple of said pressure sensor protrudes from the sensor housing container and a concave plane on its periphery. A sealing member of elastic material is caused to intervene between the flange-like mounting portion and the medium container. The sealing member is integrally molded in a first space formed between an inner wall of the opening and an outer wall of the nipple and a second space communicating with the first space and formed by the concave plane when the sensor housing container is mounted on the medium container. Thus, a pressure sensing device can be obtained which does not require redundant components for reinforcement to be added to the medium container of a thin plate for housing a measuring pressure medium.
