<p>PURPOSE:To provide a thick-film wiring board with a thick-film resistor, in which a resistance value is adjusted at a specified value and which has excellent power resistance and pulse resistance, and manufacture having the superior workability of the wiring board. CONSTITUTION:A thick-film resistor 2 is formed onto thick-film conductor patterns la, 1b oppositely shaped onto a ceramic board so as to be connected at both end sections 2a, 2b in a thick-film wiring board. The thick-film resistor 2 is formed in greater width than the thick-film conductor patterns 1a, 1b, both end sections 2a, 2b of the resistor 2 are superposed to the thick-film conductor patterns la, 1b only at central sections, and the resistor 2 has sections not superposed to the upper and lower sides of the thick-film conductor patterns 1a, 1b. The sections not superposed to the thick-film conductor patterns 1a, 1b on the upper and lower sides of the thick-film conductor patterns la, 1b are cut by trimming patterns 3 extending over the overall, length of the conductor patterns 1a, 1b from the thick-film resistor 2, sections 4 on both sides of the thick-film conductor patterns 1a, 1b are cut off, and a thick-film resistor 5, 8 resistance value of which is adjusted within a range of approximately deg.0.1% of a specified resistance value, is acquired.</p> |
