Patent ID: 8389204

Claim:
A method for producing a comb-shaped electrode, in which a positive electrode and a negative electrode are respectively formed into a comb shape and oppositely disposed so that parts of teeth of the comb shapes are alternatively arranged, the method comprising: forming a conductive layer on a surface of a substrate and patterning the conductive layer into at least a pair of comb shapes to form a current collector; coating a resist composition on the surface of the substrate containing a part of the current collector formed in the current collector forming step to form a resist layer; forming a guide hole for forming the positive electrode or the negative electrode above the current collector by irradiating a surface of the resist layer with light through a mask and developing to remove a part of the resist layer positioned above the current collector, depositing active material inside of the guide hole, and removing the resist layer formed on the guide hole after depositing the active material inside of the guide hole, wherein the resist composition is selected from the group consisting of the resist compositions (i) to (iv) below: (i) a cationic polymerization type resist composition containing a compound with an epoxy group and a cationic polymerization initiator, (ii) a novolak type resist composition containing a novolak resin and a photosensitizing agent, (iii) a chemically-amplified type resist composition containing a resin which has an acid-dissociating elimination group and increases alkali solubility when the elimination group is eliminated by action of an acid generated from a photo-acid-generating agent through exposure and the photo-acid-generating agent, and (iv) a radical polymerization type resist composition containing a monomer having an ethylenically unsaturated bond and/or a resin having an ethylenically unsaturated bond, and a radical polymerization initiator in which the number of the ethylenically unsaturated bond per molecule of the monomer is 3 or less when containing the monomer having the ethylenically unsaturated bond.
