Abstract: A liquid component sensor includes: an infrared light source; a detection cell including: two substrates made of material for penetrating an infrared light therethrough and stacked each other; a passage for flowing liquid arranged between facing surfaces of the substrates; and a detection portion for detecting the liquid provided by at least a part of the passage; a spectrometer for dispersing light penetrating the detection cell; and a light detector for detecting dispersed light. Each substrate includes outside and facing surfaces, so that two substrates provide four surfaces totally. The detection cell further includes a filter for passing the infrared light having a predetermined wavelength selectively. The filter is disposed on at least one of four surfaces at a predetermined position, which corresponds to at least the detection portion.
