<p>PROBLEM TO BE SOLVED: To provide a flexible board that exhibits sufficient durability against a load by folding and bending and suppresses increase in a resistance of a circuit formed of a conductive ink.SOLUTION: A recording card 1 as a flexible board includes: a first substrate 11a and a second substrate 11b connected via folding means 3; a first conductive circuit pattern 21 having a first wiring line 21E formed of a first conductive ink 21P printed on the first substrate 11a; a second conductive circuit pattern 22 having a second wiring line 22E formed of a second conductive ink 22P printed on the second substrate 11b; and a first connection conductive circuit pattern 24 having a connection wiring line 24E formed of a connection conductive ink 24P, connected to the first wiring line 21E and to the second wiring line 22E across the folding means 3. The connection conductive ink 24P has higher durability against folding and bending than the first conductive ink 21P and the second conductive ink 22P.</p> |
