FLEXIBLE PRINTED WIRING BOARD AND MANUFACTURING METHOD OF THE SAME

PROBLEM TO BE SOLVED: To provide a flexible printed wiring board which inhibits the increase of a contact resistance of a blind via against bending, and to provide a manufacturing method of the flexible printed wiring board.SOLUTION: A flexible printed wiring board includes: a base material 30; a first conductive pattern; a second conductive pattern; and a conductor 40 connecting the first conductive pattern with the second conductive pattern. The first conductive pattern includes a first land part 11 and the second conductive pattern includes a second land part 21 provided at the opposite side of the first land part 11 sandwiching the substrate 30 therebetween. The conductor 40 is formed by a conductive paste, fills a via hole 33 which penetrates through the first land part 11 and the base material 30 and reaches the second land part 21, and is formed so as to cover at least a part of a surface of the first land part 11. A thickness of the conductor 40 on a center axis Ca of the via hole 33 is smaller than the sum of a thickness of the base material 30 and the thickness of the first land part 11.
