摘要：
An inexpensive piezoelectric sensor where noise unlikely occurs and a method for manufacturing the same are provided. A piezoelectric body (2) made of polymeric material, a first electrode-supporting portion (3) disposed at one side of the piezoelectric body (2) and supporting a signal electrode (3b) on a first insulator (3a), and a second electrode-supporting portion (4) disposed at the other side of the piezoelectric body (2) and supporting a ground electrode (4b) on a second insulator (4a) are included, and the first electrode-supporting portion (3) and the second electrode-supporting portion (4) are arranged so that the signal electrode (3b) and the ground electrode (4b) overlap each other in a layering direction.
