PROBLEM TO BE SOLVED: To provide a respiration sensor for achieving respiration measurement in a natural state of a measurement object person by eliminating a stress to the measurement object person in respiration measurement.SOLUTION: A respiration sensor 10 includes electrodes 11 and 12 (first electric conductor and second electric conductor) arranged on a first point 91A and a second point 91B in a breast body surface area 91 (first body surface area) of a measurement object person 90. The electrode 12 is separated from the electrode 11, and is adjacent to the electrode 11. Furthermore, the respiration sensor 10 includes an analyzer 13 (first detection means) which demands a change in an electrostatic capacitance between the electrodes 11 and 12, and detects the respiration of the measurement object person 90 from the change in the electrostatic capacitance.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】呼吸計測の際に計測対象者にかかるストレスをなくして、計測対象者の自然な状態での呼吸計測を実現させる呼吸センサの提供。【解決手段】呼吸センサ10は、計測対象者90の胸部体表領域91(第1の体表領域)における第1のポイント91Aおよび第2のポイント91Bに配設される電極11、12(第1の電気伝導体、第2の電気伝導体)を備える。電極12は電極11とは別体とされて、この電極11に隣り合う。また、呼吸センサ10は、各電極11、12の間における静電容量の変化を求め、この静電容量の変化から計測対象者90の呼吸を検知する解析装置13(第1の検知手段)を備える。【選択図】図1
