To provide a delay line for a high-frequency substrate circuit which has a small circuit scale and simple manufacturing process, and to provide a method of manufacturing the delay line for a high-frequency substrate circuit.

In the case of microstrip line, a print capacitor 14 is provided for a prescribed part in contact with a central conductor 13. In the case of triplate line, an upper ground layer with a dielectric layer 25 of a central conductor 23 in between is etched and an exposure part 26 is provided, and the exposure part 26 is provided with a print capacitor 24. The print capacitor adjusts a capacitor paste by distributing a dielectric to resin and the like, prints the capacitor paste to an area of prescribed thickness and a prescribed size, hardens it, and forms it.
