Abstract
In a body cavity insertion-type ultrasound probe, acoustic matching between each transducer and a living body is improved. A film member (FPC substrate) is configured with a base film and a conductor layer. The conductor layer includes a signal pattern, a ground pattern, and a plurality of acoustic element arrays. An acoustic matching layer is provided between each transducer and the base film. The acoustic matching layer consists of an acoustic element array and a filling material. A ratio of a conductor material in the acoustic matching layer determines an acoustic impedance of the acoustic matching layer.
