PURPOSE: A pressure sensor and a structure for attaching the same are provided to reduce the number of parts and the number of processes. CONSTITUTION: A pressure sensor comprises a case(10), a detecting unit, a housing member(50), and a diaphragm. The detecting unit is attached to one end of the case. The housing member comprises a first connecting part(51), a second connecting part(52), a path, a pressure introducing hole(54A) and a first plane connecting to one end of the case. The diaphragm is fixed to the housing member in order to cover the detecting unit. The first and second connecting parts are connected to a pipe through which the refrigerant flows. The path connects the first connecting part to the second connecting part. The pressure introducing hole introduces the pressure of the refrigerant from the path to the diaphragm. The detecting unit is introduced through the path and the pressure introducing hole from the first and second connecting parts. The pressure of the refrigerant, which is applied to the diaphragm and is transferred to the detecting unit, is detected. The housing member has a hexahedron type. The case is arranged on one of the top and the bottom of the housing member. The first and second connecting parts are respectively arranged on sides which the housing member faces.
