An ear microphone comprising a pickup piece having a configuration which facilitates insertion thereof into a human external auditory canal, a vibration/electrical signal converter element installed within the pickup piece, a resilient member attached to the pickup piece, and a support body to support the pickup piece by way of the resilient member. The pickup piece and support body are of a rigid material having a large mass whereas the resilient member has a large resiliency. The converter element has a lead wire extending therefrom through the pickup piece, the resilient member, and the support body for signal processing outside the ear microphone.
