A photosensitive resin composition is here disclosed which satisfies the following (1) and (2): (1) when a 1.0 wt % aqueous sodium carbonate solution is sprayed by a spray on a layer of the photosensitive resin composition having a thickness of 37 to 42 μm under the following conditions, the photosensitive resin composition layer being able to be removed within 20 seconds, the above conditions being that an internal diameter of a nozzle of the spray is 1.2 mm, a spraying pressure is 0.05 MPa, and a distance between a point of the spray nozzle which is closest to the photosensitive resin composition layer and the photosensitive resin composition layer is 50 mm; and (2) when the 1.0 wt % aqueous sodium carbonate solution is sprayed three times for 36 seconds under the above conditions on a cured film obtained by laminating a layer of the photosensitive resin composition having the above thickness on a copper-clad laminate having 18 three-continuous holes in which 3 holes each having a diameter of 6 mm are continuously integrated and which has a length of 16 mm, and then photo-curing the layer with an exposure capable of curing 24 steps in a 41-step tablet, the number of holes where the cured film is broken being 5 or less.
