PRINTED WIRING BOARD AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To obtain a printed board that is mounted with a resistor and has excellent characteristics. SOLUTION: This printed board is obtained by forming a resistance body 13 by printing resistor paste on copper foil 11 and drying the paste. Then the copper foil 11 is laminated upon a prepreg 14 by pressing the foil 11 against the prepreg 14 with the resistance body 13 formed on the foil 11 on the prepreg 14 side together with another copper foil 15. In addition, a conductor layer (circuit pattern) 2 containing electrodes 4 for resistor is formed by patterning the foil 11. The main body 1 of this printed board has a recessed section having a flat bottom face and filled up with a resistance body 3. The electrodes 4 are separately connected to the resistance body 3. The resistance body 3 and electrodes 4 constitute the resistor 5.
