Glitter pigment, pigment-containing composition, and pigment-containing painted product

The present invention provides a glitter pigment suitable for imparting high brightness to reflected light toward a regular reflection direction and reducing unnaturalness caused by an observation angle-dependent variation in reflected light. The glitter pigment according to the present invention includes: a flaky substrate; an optical interference film formed on a surface of the flaky substrate; and fine light scattering particles attached to the optical interference film, wherein reflected light is represented by an L*(15) value of more than 100, a ΔL*(h−s) value of less than 30, and a Δh(h−s) value of less than 40° in an L*C*h color system. The L*(15) value is an L* value of the reflected light toward a 15° direction based on an angular representation in which, when an illuminant is disposed so that an incident angle is 45°, an angle at which light is regularly reflected is defined as 0° and a light incident direction is defined as positive. The ΔL*(h−s) value is a difference in L* between a highlight and shade, and the Δh(h−s) value is a difference in h between a highlight and shade. The Δh value expressed in angle is an angular difference. The highlight is an average of values measured at 15° and 25°, and the shade is an average of values measured at 75° and 110°.
