    摘要: Disclosed are a highly reliable circuit board and a method of stably manufacturing the circuit board, wherein an insulator made from a specific organic insulating material is provided under a highly stressed conductor for preventing occurrence of cracks in the insulator. In addition, a method of correcting a wiring of a ceramic board is additionally adopted. The circuit board includes a thick film wiring board 1 having a first conductor pattern 2 and a thin film layer laminated on the first conductor pattern 2. The thin film layer includes a first insulator 5 on the first conductor pattern 2; a second insulator 10 on the first insulator 5; a second conductor pattern 8 formed on the first insulator 5 in such a manner as to partially pass through the first insulator 5 and to be electrically connected to the first conductor pattern 2; a wiring pattern 9 for circuit correction formed on the first insulator 5; and a third conductor pattern 11 passing through the first insulator 5 and the second insulator 10 and electrically connected to the second conductor pattern 8.
