The epitaxial junction type tabular grains each satisfying the following requirements (i) to (iv) occupy 100 to 50% (grain numerical ratio) of all the grains contained in the silver halide photographic emulsion: (i) host tabular grain is a tabular grain of silver iodobromide or silver iodochlorobromide having {111} faces as main planes and two parallel twin planes; (ii) at least one silver halide epitaxial portion is formed, per grain, only on a corner portion of the host tabular grain; (iii) a portion of an external surface of the silver halide epitaxial portion has a face parallel to the main plane of the host tabular grain; and (iv) a portion of an external surface of the silver halide epitaxial portion has a {100} face.
