PROBLEM TO BE SOLVED: To provide: a flexible circuit board which enables a new image expression, which raises the value and is improved in power for appealing to customers; and a printer device for producing such a flexible circuit board.SOLUTION: A flexible circuit board 20B comprises: a flexible board 1; a receiving layer 2 formed on the board 1, and including at least alumina or silica which has an average primary particle diameter of 150 nm or less, preferably an average primary particle diameter of 50 nm or less; and an electrical circuit pattern formed in the receiving layer 2 on the board 1 from a conductive material. In the flexible circuit board 20B, the electrical circuit pattern includes wiring lines 6 formed from the conductive material, an ultraviolet light LED 8, and a button battery 9. The electrical circuit pattern and a fluorescence image 7 is formed in the receiving layer 2 on the board 1.SELECTED DRAWING: Figure 4 |
