A flexible transducer that generates a stronger electrical signal for movement in a specific direction, and a device using the signal from the transducer and / or functions by inputting an electrical signal. Provide a device. A conductive fiber B and a piezoelectric fiber A include a piezoelectric unit disposed on substantially the same plane so as to be electrically connected. The piezoelectric fiber A mainly includes polylactic acid, and wide-angle X-ray diffraction. Homo PLA crystallinity X homo (%) and crystal orientation A (%), which are quantified by analysis (WAXD), satisfy the formula (1). X homo × A × A ÷ 10 6 ≧ 0.26 (1) [Selection] Figure 1 |
