Zusammenfassung:A pressure detection device (10) comprises a pressure detection element (21) which receives pressure so as to output a detection signal corresponding to the pressure and a processing circuit (30) which processes and outputs the detection signal output from the pressure detection element. A processing circuit (30) is adopted which includes at least one or more amplifier circuits which amplify an output signal (Vout21) from an integrator circuit and a base voltage adjustment circuit (40) which is connected between a supply portion of a reference voltage (Vr) fed to the amplifier circuit and an input terminal of at least one of the amplifier circuits and which adjusts the magnitude of a base voltage (Vb22) that is a potential when a detection signal (Qi) in an output signal (Vout22) output from the amplifier circuit is not present.
