Electromagnetic wave sensor (infrared sensor) has a first substrate; a second substrate that faces the first substrate and that allows infrared rays to pass through at least a part of the second substrate; first circumferential wall that is positioned between the first substrate and the second substrate and that forms first space together with the first and second substrates; bolometer structures that are provided in first space; first measuring element that is provided in first space and that is used for taking a first measurement relating to pressure in first space; and a monitoring portion. The monitoring portion acquires the first measurement that is taken using first measuring element and outputs a predetermined signal indicating an abnormality based on at least the first measurement.
