<p><P>PROBLEM TO BE SOLVED: To obtain a high frequency printed wiring board capable of preventing a signal from being reflected owing to a change in characteristic impedance of a conductor pattern to reduce transmission loss. <P>SOLUTION: On a board 1, there are provided first and second conductor patterns 2a, 2b at a predetermined interval between one ends thereof; a printed resistor 4 connected between the one ends of the first and second conductor patterns 2a, 2b; and printed resistor forming mold parts, in which a pair thereof are provided along a part other than the first and second conductor patterns 2a, 2b on the board 1 such that they have substantially the same size as a height from a portion on the board 1 to the top of a printed resistor 4, and come into contact with two side surfaces of the printed resistor 4 in an outer periphery of the same excepting a connection portion between the first and second conductor patterns 2a, 2b, and further they employ a solder resist 3 comprising an epoxy resin restricting the configuration of the printed board 4. <P>COPYRIGHT: (C)2003,JPO</p> |
