Abstract:
1. A method for manufacturing an electronic circuit component comprising the steps of: heating a layer containing at least one of a polyimide and a precursor thereof at a temperature of 200° C. or lower to form an insulating layer having a contact angle with water of 80° or more, and forming a coating film comprising a dispersion containing metal nanoparticles on the insulating layer and heating the coating film at a temperature of 200° C. or lower to form a conductive layer, wherein said polyimide and the precursor thereof include at least one of repeating units represented by formula (1) and formula (2): in which A in formula (1) and formula (2) is a tetravalent organic group represented by formula (3): wherein R B represents a divalent organic group, and 10 to 100 mol % of B is a group represented by formula (4): wherein X
