<P>PROBLEM TO BE SOLVED: To provide a sensor device and a pulse sensor which are capable of surely detecting a body motion and preventing a false report by removing an influence of noise such as vibrations. Ž<P>SOLUTION: This sensor device includes a hollow main chamber 1, microphones 21 and 22 that have vibrating plates 2b communicating with the interior of the main chamber 1 by sealing an opening provided in the main chamber 1, and outputs signals generated by the displacement of the vibrating plates 2b, and a signal processing section 3 in which respective outputs of the microphones 21 and 22 are input, wherein the signal processing section 3 determines whether or not the main chamber 1 is deformed to change the pressure in the main chamber 1 based on the respective outputs of the microphones 21 and 22.
