Inorganic and organic composite materials have been utilized as high‐functional materials over a wide variety of industrial fields. Understanding interactions between inorganic and organic components is important for their further improvements. In this study, hydroxyapatite (HAp) nanoparticles synthesized with sodium dodecylphosphate (SDP) were evaluated using gentle‐SIMS (G‐SIMS) and g‐ogram, which are spectrum analysis methods for time‐of‐flight SIMS. As a result, G‐SIMS and g‐ogram indicates that SDP molecules are adsorbed onto the surface of HAp nanoparticles and partly used to form HAp nanostructures. The more intact fragment ions indicated by G‐SIMS and g‐ogram imply that lamellar structures are formed in HAp sample synthesized with the high SDP concentration. Therefore, it is suggested that G‐SIMS and g‐ogram provide useful information for understanding chemistry of fine structures within inorganic and organic composite materials.
