A pressure sensor for a fuel injection device capable of accurately and stably introducing, through a negative pressure introduction path, a pressure generated in a suction air passage into a pressure receiving chamber where the pressure sensor is stored and capable of changing a response speed of the pressure introduced to the pressure receiving chamber, with the structure such that a pressure receiving chamber (9) is formed airtightly by a first casing (5) and a second casing (6), the pressure in a suction air passage (2) is introduced into the pressure receiving chamber (9) through a negative pressure introduction path (P), and the first casing (5) and the negative pressure introduction path (P) are integrally formed with a throttle body (1) or a suction air pipe(10). |
