Current detecting sensor and method of fabricating the same

A current detecting sensor comprising:

• (a) an insulating substrate;
• (b) a first electrode formed on said insulating substrate,
• said first electrode comprising an electrically conductive electrode and a plurality of metal islands formed on said electrically conductive electrode, said metal islands each having a smaller area than a area of said electrically conductive electrode;
• (c) a second electrode formed on said insulating substrate, said second electrode surrounding said first electrode therewith;
• (d) a third electrode formed on said insulating substrate;
• (e) an insulating protective film covering said insulating substrate therewith and further covering at least edges of said first, second and third electrodes therewith, said insulating protective film being formed with first, second and third openings at upper surfaces of said first, second and third electrodes, respectively;
• and
• (f) an organic film covering said first to third electrodes and said insulating protective film therewith.

A method of fabricating a current detecting sensor, comprising the steps of:

• (a) forming first to third electrodes on a substrate, said first electrode being comprised of an electrically conductive electrode and a metal layer formed on said electrically conductive electrode, said metal layer having a smaller area than a area of said electrically conductive electrode, said second electrode being comprised of an electrically conductive electrode, said third electrode being comprised of an electrically conductive electrode;
• (b) depositing an insulating protective film over a product resulting from said step (a);
• (c) patterning said insulating protective film in such a manner that said insulating protective film covers said substrate therewith and further covers at least edges of said first, second and third electrodes therewith, and that said insulating protective film has first, second and third openings at upper surfaces of said first, second and third electrodes, respectively;
• and
• (d) covering a product resulting from said step (c) with an organic film.
