Method of electrically connecting element to wiring, method of producing light-emitting element assembly, and light-emitting element assembly

A method of electrically connecting an element to wiring comprising:

• (A) forming a conductive fixing member precursor layer on a connecting portion provided on an element;
• and
• (B) arranging the element on wiring provided on a base such that the conductive fixing member precursor layer contacts the wiring, and then heating the conductive fixing member precursor layer to form a conductive fixing member layer, thereby fixing the connecting portion of the element to the wiring, with the conductive fixing member layer therebetween,
• wherein the conductive fixing member precursor layer is composed of a solution-type conductive material.

A method of producing a light-emitting element assembly comprising:

• (A) forming a conductive fixing member precursor layer at least on wiring provided on a base;
• and
• (B) arranging a light-emitting element having a connecting portion on the wiring such that the connecting portion contacts the conductive fixing member precursor layer, and then heating the conductive fixing member precursor layer to form a conductive fixing member layer, thereby fixing the connecting portion of the light-emitting element to the wiring, with the conductive fixing member layer therebetween,
• wherein the conductive fixing member precursor layer is composed of a solution-type conductive material.
