Abstract
Each of transducers of a touch panel device includes a piezoelectric thin film, a plate electrode disposed at one surface of the piezoelectric thin film and a comb-like electrode disposed at the other surface of the piezoelectric thin film. The comb-like electrode has a plurality of comb-like electrode fingers and a linear bus electrode to which one end of each of the plural comb-like electrode fingers is connected. A plurality of wiring electrodes is provided at the outer side of any of the transducers in parallel with the bus electrode of the transducer and is connected to the bus electrode and the plate electrode of any of the transducers. Each of the wiring electrodes includes an electrode base portion formed by printing silver paste containing fine particles on the substrate and an electrode main body formed by printing silver paste containing large particles and fine particles in a mixed manner on the electrode base portion.
