PROBLEM TO BE SOLVED: To provide an in-ear information acquiring apparatus where a sensor can stably face an eardrum and the aspect of the sensor can be held constant even when used for a long period of time, in a thermometer which measures radiant heat of the eardrum.SOLUTION: The in-ear information acquiring apparatus includes: an information acquiring unit that is inserted in the external auditory canal and acquires information inside the earhole and a fixing mechanism that fixes the information acquiring unit inside the external auditory canal. The fixing mechanism has: a rod portion that covers a wire connected to the information acquiring unit and extending to the inlet side of the external auditory canal, and on the outside surface of which a plurality of support portions warping up toward the eardrum and erecting toward the wall surface of the external auditory canal are provided along the outer periphery thereof at least at one location in the external auditory canal direction and an adjusting portion that adjusts an erect state of the support portions provided on the rod portion.COPYRIGHT: (C)2013,JPO&INPIT【課題】鼓膜の放射熱を測定する温度計において、鼓膜に対して安定的にセンサを対向させることができ、長時間使用しても当該センサの向きを一定に保持できる耳孔内情報取得装置を提供する。【解決手段】本技術に係る耳孔内情報取得装置は、外耳道内に挿入され、耳孔内における情報を取得する情報取得部と、情報取得部を外耳道内で固定する固定機構と、を備え、固定機構は、情報取得部と接続され外耳道入口側へ延びるワイヤを覆い、外耳道方向の少なくとも1箇所において、鼓膜に向かって反り上がり外耳道の壁面に向かって起立する複数の支持毛が外周に沿って外側面に設けられるロッド部と、ロッド部に設けられた支持毛の起立状態を調整する調整部と、を有する。【選択図】図1
