A lithographic printing plate precursor comprising, on a support, an image recording layer, and an undercoat layer provided between the support and the image recording layer, the undercoat layer containing a polymer compound composed of repeating units, the polymer compound having, at the terminal of the principal chain thereof, a group represented by the formula: in the formula, B represents a linkage residue linking the terminal of the principal chain of the polymer compound with the radical-polymerizable ethylenic unsaturated group, each of R 1 to R 3 independently represents a hydrogen atom, alkyl group or aryl group, the broken line represents a linkage to the principal chain of the polymer compound, Y 2 represents a single bond or divalent linking group, n represents an integer of 1 or larger, -X- represents -O-, or -(NR 4)-, R 4 represents a hydrogen atom, alkyl group or aryl group, and each repeating unit having, as a side chain bound to the principal chain, one or more groups selected from support-adsorptive groups represented by the formulae to below: in the formulae to, each of M 1 to M 10 independently represents a proton, metal cation, ammonium, phosphonium, iodonium, sulfonium, diazonium, or azinium, each of R 1 to R 44 independently represents a hydrogen atom, alkyl group, aryl group, alkynyl group, or alkenyl group, at least one of R 29 to R 44 is a bond to a linking group coupled to the principal chain of the polymer compound, and each of the residuals represents a hydrogen atom, halogen atom, cyano group, nitro group, or monovalent linkage residue, X - represents a counter anion and the broken line represents a bond to a linking group coupled to the principal chain of the polymer compound. in the formula, B represents a linkage residue linking the terminal of the principal chain of the polymer compound with the radical-polymerizable ethylenic unsaturated group, each of R 1 to R 3 independently represents a hydrogen atom, alkyl group or aryl group, the broken line represents a linkage to the principal chain of the polymer compound, Y 2 represents a single bond or divalent linking group, n represents an integer of 1 or larger, -X- represents -O-, or -(NR 4)-, R 4 represents a hydrogen atom, alkyl group or aryl group, and each repeating unit having, as a side chain bound to the principal chain, one or more groups selected from support-adsorptive groups represented by the formulae to below: in the formulae to, each of M 1 to M 10 independently represents a proton, metal cation, ammonium, phosphonium, iodonium, sulfonium, diazonium, or azinium, each of R 1 to R 44 independently represents a hydrogen atom, alkyl group, aryl group, alkynyl group, or alkenyl group, at least one of R 29 to R 44 is a bond to a linking group coupled to the principal chain of the polymer compound, and each of the residuals represents a hydrogen atom, halogen atom, cyano group, nitro group, or monovalent linkage residue, X - represents a counter anion and the broken line represents a bond to a linking group coupled to the principal chain of the polymer compound. each of M 1 to M 10 independently represents a proton, metal cation, ammonium, phosphonium, iodonium, sulfonium, diazonium, or azinium, each of R 1 to R 44 independently represents a hydrogen atom, alkyl group, aryl group, alkynyl group, or alkenyl group, at least one of R 29 to R 44 is a bond to a linking group coupled to the principal chain of the polymer compound, and each of the residuals represents a hydrogen atom, halogen atom, cyano group, nitro group, or monovalent linkage residue, X - represents a counter anion and the broken line represents a bond to a linking group coupled to the principal chain of the polymer compound.
