    Abstract: An object of the present invention is to provide a wiring substrate capable of accurately detecting a potential difference in a shunt resistor and a current to be detected without being influenced by soldering, and a current detection device. A land mounted with a rectangular surface at each end of a shunt resistor is configured by first and second lands each having a rectangular portion and being arranged at a predetermined interval with a central line as a center, and third and fourth lands each having an area smaller than those of the first and second lands and being arranged at one end of the first and second lands to be connected respectively to the first and second lands. A wiring pattern for detecting a potential difference between the both ends of the shunt resistor is configured by a first wiring pattern connected to the third land and pulled out from the third land towards the fourth land, a second wiring pattern connected to the fourth land and pulled out from the fourth land towards the third land, and third and fourth wiring patterns connected respectively to the first and second wiring patterns and pulled out into one direction.

    Abstract: In a fitting region for a SAW filter which includes langasite as its piezoelectric element, there are included an input side terminal electrode and an output side terminal electrode which are connected to an input terminal and to an output terminal of the SAW filter. To each of the terminal electrodes, at a position which is separated by just a predetermined distance from the fitting region of the SAW filter, there is connected a micro strip line which extends in mutually opposite directions along a direction which is parallel to the transmission direction of a frequency signal within the SAW filter. A slit is provided in the fitting region of the SAW filter and extends in a direction which intersects the transmission direction of the frequency signal within the SAW filter. A plurality of through holes are provided in the printed substrate and electrically connect together its surface and its rear surface which is grounded. Furthermore, there is provided a protective member which has a conductive surface and which is in contact with the surface of said filter, and said conductive surface of said protective member which is in contact with the surface of said filter is set so as to be of the same size as the surface of said filter, or so as to be smaller than it.
