ELECTROSTATIC CAPACITANCE TRANSDUCER, PROBE, AND SUBJECT INFORMATION ACQUIRING DEVICE

摘要

An electrostatic capacitance transducer includes: multiple elements each having a cell including a first electrode, and a vibrating film including a second electrode, formed across a gap from the first electrode; a first flexible printed circuit having multiple first lines; and a second flexible printed circuit having multiple second lines. Part of the multiple elements are grouped into a first element group, each one thereof being electrically connected to a different one of the first lines. Part of the multiple elements other than the first element group are grouped into a second element group, each one thereof being electrically connected to a different one of the second lines. The intervals between adjacent lines in at least part of the plurality of first and second lines are wider at an opposite side from a connection side where the lines have been connected to the multiple elements, than at the connection side.
