PROBLEM TO BE SOLVED: To provide a pressure detector capable of high pressure measurement of gas, with simple constitution of low cost. SOLUTION: A semiconductor pressure sensor 4 is arranged in an accommodating part 4, and detects the pressure of fluid applied from an aperture part of the accommodating part 4. Lead pins (lead part) 9 are arranged in the vicinity of the sensor 4 of the accommodating part 4. Lead wires 10 connect electrically the lead pins 9 with the sensor 4. A gel type member (first protective member) 11 covers a diaphragm (pressure receiving part) of the sensor 4, and makes it possible to detect the pressure of fluid with the pressure receiving part. Protective member (second protective member) 12 covers a part of the sensor which is not covered with the gel type member 11, lead pins 9 and the connection wires 10, and is harder than the gel type member 11.
