摘要

A method of manufacturing a wiring board comprising (A) a substrate having a groove and an adjacent area adjacent to the groove and (B) a first wiring having a first portion and a second portion extending from the first portion, the first portion being provided in a first area in the groove and the second portion being provided in a second area which is part of the adjacent area, the method comprising steps of: preparing a substrate having a groove; making a contact angle of the second area different from a contact angle of a third area which is another part of the adjacent area, surrounding the second area together with the groove; and applying conductive paste to at least an interior of the groove and part of the adjacent area.
