Abstract
An optical switch includes a film consisting of a polymer, a keep plate having a switching through hole and a driver. The film has a core linearly extending therein and a notch extending across a switching portion located halfway in the core. The keep plate holds the film to expose the switching portion at the through hole. The driver is employed for narrowing and separating a gap of the notch, thereby selecting a route of light. The notch is formed by precedently forming a starting groove on the surface of the film and pressing the switching portion with a pressing member from the backside of the starting groove while holding the film with the keep plate thereby causing cleavage.
