Glass ceramic body, laminate, housing for portable electronic equipment, and portable electronic equipment

Provided are: a glass ceramic body that has sufficiently high strength and a high degree of freedom in shape so as to be able to conform to three-dimensional shapes; and a laminate including said glass ceramic body. This glass ceramic body includes flat alumina particles dispersed in a glass matrix comprising a glass with a degree of crystallinity of 25% or less, wherein: the flat alumina particles are dispersed in the glass matrix such that the thickness direction of each particle is in a direction substantially perpendicular to the planar direction of one of the surfaces of the glass ceramic body; in a cross section of the glass ceramic body taken along the thickness direction of the flat alumina particles, the total cross-sectional area of flat alumina particles each with a cross section having a thickness of 0.2 [mu]m or greater, a maximum diameter of 8 [mu]m or smaller, and an aspect ratio within the range of 3-18 is 20% or greater with respect to the entire area of said cross section; and the open poros
