There is provided a behind-the-ear hearing aid that makes it easy for a hearing aid wearer to estimate a position of a sound source with respect to a front-back direction and that enables an increase in aesthetic property when the hearing aid is worn. A behind-the-ear hearing aid of the present invention is used while fitted to an ear of a human body, and includes at least a microphonewhich collects ambient sound, thereby generating an input signal and signal processing unitthat generates an output signal from the input signal. The hearing aid also has a behind-the-ear portionthat can be fitted to the ear and a receiverthat reproduces output sound from the output signal. When the behind-the-ear portionis fitted to the ear, the microphoneis arranged in an entrance of an ear canal that lies in the extension of an ear canaland that is disposed closer to an eardrum than to a plane that is defined by a helix, a tragus, and an earlobe
