Date Apr. 2, 1993.Provided is a microstrip line that permits a large current flow while maintaining a high characteristic impedance. The microstrip line, comprising a dielectric substrate (10), a grounded conductor (12), and a conducting strip (14), includes an upper conductor (16) formed substantially along the centerline of the conducting strip (14) and having a vertically elongated cross section such that a width w1 of a base (16a) of the cross section is smaller than the width W of the conducting strip (14), while a width w2 of a portion extending from the base (16a) to its opposing side (16b) is substantially equal to the width w1 of the base (16a) or gradually increases toward an upper portion. The upper conductor (16) having such cross section is formed by heat bonding a gold, silver, or copper wire, etched into a desired cross section, onto the conducting strip (14), or by depositing gold, silver, or copper by plating onto the conducting strip.
