The present invention provides a bis(4-mercaptophenyl) sulfide derivative represented by general formula 1. This derivative is a monomer that can form a dielectric film suitable for an electronic component. The present invention further provides a method for producing this derivative and an electronic component having high characteristics under excellent humidity and high temperature.

Capacitor comprising bis(4-mercaptophenyl) sulfide derivative

A capacitor ( ) using a flexible substrate ( ) includes a hole portion ( ) formed in a dielectric ( ) to connect an upper electrode ( ) to an external leader electrode ( ). At least part of the hole portion ( ) extends from its lower end to upper end at an inclination between 0.1 and 20&deg; with respect to a top surface of the external leader electrode ( ). Then, an upper end corner of an inclined wall surface of the upper electrode ( ), which inclines along the hole portion ( ) of the dielectric ( ), has a downward inclination between 0.1 and 20&deg;. A lower end corner of the inclined wall surface of the upper electrode ( ), which inclines along the hole portion of the dielectric ( ), has an upward inclination between 0.1 and 20&deg;. As a result, stress concentration on the corners of the upper electrode ( ) is drastically reduced to prevent the upper electrode ( ) from cracking.
