PROBLEM TO BE SOLVED: To provide an inorganic pigment dispersing agent excellent in long period dispersing stability in a micronized inorganic pigment of high concentration slurry and an inorganic pigment dispersion composition containing the same. SOLUTION: The inorganic pigment dispersing agent containing a monomer-component copolymer containing a monomer 1 expressed by the formula (1), a monomer 2 expressed by the formula (2), and a monomer 3 expressed by the formula 3, wherein R<SP>1</SP>, R<SP>2</SP>, R<SP>4</SP>, and R<SP>5</SP>independently represent H or a methyl group, R<SP>3</SP>, R<SP>6</SP>, and R<SP>7</SP>represent a C2-12 alkylene group, m<SB>1</SB>, m<SB>2</SB>, and m<SB>3</SB>represent the number of 1-30, and M<SP>1</SP>, M<SP>2</SP>, M<SP>3</SP>, and M<SP>4</SP>represent H or a cationic group. The inorganic pigment dispersing agent containing the dispersing agent and the inorganic pigment is also disclosed. COPYRIGHT: (C)2007,JPO&INPIT
