PROBLEM TO BE SOLVED: To determine an n-th peak frequency fn in a frequency characteristic of a delay time at the design stage by utilizing a relational equation where the n-th peak frequency fn in a frequency characteristic of a delay time depends on a light velocity, a specific dielectric constant of a dielectric layer and length of opposed line segments of a transmission line independently of the difference from the specific dielectric constant. SOLUTION: The delay line 10 is formed by using rectangular sheet layers 16a-16d made up of dielectric layers whose major components are magnesium oxide and silica as a laminated body and providing terminals or the like around the layers. The sheet layer 16a is an uppermost layer, the lower sheet layer 16b has a ground conductor 17 on its upper side. The sheet layer 16c under the sheet layer 16b has a meandering transmission line 18 folded in a meandering way on its upper side, the lower sheet layer 16d has a ground conductor 19 on its upper side. An input terminal 12, an output terminal 13 and ground terminals 14, 15 are formed to four side faces of the laminator of the sheet layers. |
