Measuring apparatus and measuring method

A biological information measurement apparatus includes a biological sensor and an insertion portion, and the biological sensor is disposed at a position opposite the concha when the insertion portion is inserted in the external ear canal.

Biological information measurement apparatus

There has been no sufficient study to address an issue caused in the use of an open-air type audio device. Therefore, provided is an audio device with an actually useful organism sensor. In particular, the audio device includes an audio unitto externally abut on the ear without being inserted thereinto, and an organism sensor unitto be inserted into the ear.

Audio device
