Abstract
A laminated body is formed. The laminated body includes layers. One of the layers includes a piezoelectric array. The laminated body is engaged with both a pressing film and a curved member having a curved outer surface. A tension is exerted on the pressing film to press the laminated body against the curved outer surface of the curved member so that the laminated body is bent along the curved outer surface of the curved member. The use of the pressing film may be replaced by a process in which at least one of the layers is subjected to a tension to bend the laminated body.
