Method for producing conductive member, and conductive member

A method for producing a conductive member comprising:

• forming a first silver halide emulsion layer, a light absorption layer, and a second silver halide emulsion layer on a transparent support in this order;
• and
• performing pattern exposure on the first silver halide emulsion layer and the second silver halide emulsion layer and applying a development treatment thereto to obtain a conductive layer including a thin metal wire,
• wherein the timing of light exposure of the first silver halide emulsion layer is the same as that of the second silver halide emulsion layer, and a pattern in which the first silver halide emulsion layer is exposed to light is different from a pattern in which the second silver halide emulsion layer is exposed to light, at least in part, in the performing of the pattern exposure on the first silver halide emulsion layer and the second silver halide emulsion layer,
• wherein the spectral sensitivity of the first silver halide emulsion layer is different from the spectral sensitivity of the second silver halide emulsion layer, and the first silver halide emulsion layer and the second silver halide emulsion layer are respectively exposed to light having wavelengths different from each other, from one side of a front surface and a rear surface of the transparent support, and
• wherein the light absorption layer absorbs at least a part of the wavelengths of light to which the first silver halide emulsion layer or the second silver halide emulsion layer is exposed, and the light absorption layer absorbs either of the light having wavelengths different from each other.
