<p>PROBLEM TO BE SOLVED: To provide a method of manufacturing a circuit board capable of preventing electrostatic breakdown in a circuit part by improving a short circuit part that short-circuits wiring for protection extending along a predetermined division line with terminals.SOLUTION: When an element substrate 10 used for an electro-optic device is manufactured, a circuit part 11, a plurality of terminals 102, and reactance elements 321 are formed in respective areas of a mother substrate 300 in a first process. In a second process, wiring 310 and 328 are formed for electrically connecting adjacent circuit parts 11 with each other via the reactance element 321. In a third process, the mother substrate 300 is cut along a predetermined division line 303.</p> |
