A light, flexible, and tough thin film having high total light transmittance that can be formed on various three dimensional shapes, and also provides a stably driven tactile sensor, which is an electronic device having the switching function thereof, is provided. The tactile sensor is formed on a polyimide thin film having high total light transmittance, thermal resistance, and a polar component of surface free energy with a specific value, and has a switching device that emits a voltage signal which, through an electronic circuit for controlling noise, stably drives another device. This tactile sensor has a curved or flat surface and has a first electrode, a ferroelectric layer, and a second electrode formed over the polyimide thin film. The switching device as a tactile sensor can drive another device merely by a light touch with a finger, and can be manufactured at a high non-defective rate.

The present invention provides an insulating layer for printed circuit boards having a difference of within 20% between the flexural modulus at 25 C. and the flexural modulus under heat at 250 C.
