<P>PROBLEM TO BE SOLVED: To provide a high frequency substrate that easily adjusts an insertion loss of substrate wiring lines even after wiring lines are arranged. <P>SOLUTION: Slits 5-1 to 5-6 are created at positions opposite to a signal line 4 on a GND layer 1. When an insertion loss of the high frequency substrate is adjusted, the slits 5-1 to 5-6 are closed with a conductive resin 6. The conductive resin 6 slightly transmits electricity, so that signals leak through the conductive resin 6 that closes the slits and the electric power of transmission signals decreases. Thereby, the insertion loss of the high frequency substrate is increased by closing the slits 5-1 to 5-6 with the conductive resin 6. <P>COPYRIGHT: (C)2009,JPO&INPIT |
