PROBLEM TO BE SOLVED: To provide a wiring board excellent in a conductive property and an ion migration suppression function of a wiring layer.SOLUTION: A wiring board comprises: an insulation substrate; and a wiring layer including a first metal layer arranged on the insulation substrate and a second metal layer arranged so as to cover a surface of the first metal layer, which does not contact the insulation substrate. A thickness of the second metal layer is 1/10 of an entire thickness of the wiring layer. The wiring layer includes a migration inhibitor in which a mass Y of the migration inhibitor included in the second metal layer is larger than a mass X of the migration inhibitor included in the first metal layer.

PROBLEM TO BE SOLVED: To provide a photosensitive resin composition suitable for forming a solder resist excellent in insulating property as well as in folding resistance.SOLUTION: The photosensitive resin composition comprises (A) an acid-modified ethylenically unsaturated group-containing polyurethane resin, (B) a radical polymerizable compound, (C) a thermal crosslinking agent and (D) a photopolymerization initiator having two oxime ester groups in the molecule. The (A) polyurethane resin has a partial structure expressed by general formula (U1). In general formula (U1), Lrepresents a divalent connecting group including neither an ethylenically unsaturated group nor a carboxyl group.
