To provide a differential pressure transmitter that has a small number of parts and can be easily maintained.
In the differential pressure transmitter equipping with first and second pressure reception chambers 201 and 202 for transmitting a pressure from first and second diaphragms 6 and 7 to first and second detection fluids, and a differential pressure detection sensor 2 for obtaining the differential pressure between first and second measurement fluids being applied to the first and second diaphragms by receiving the pressure of the first and second detection fluids, a first measurement fluid pressure reception chamber for guiding the pressure of the first measurement fluid to the first diaphragm 6 is composed, a second measurement fluid pressure reception chamber for guiding the pressure of the second measurement fluid to the second diaphragm 7 is composed by the pressure reception member of the differential pressure transmitter for forming the second pressure reception chamber 202, and first and second pressure-guiding ports that are joined to piping for transferring the pressure of the first and second measurement fluids are provided at the first and second measurement fluid pressure reception chambers.
