A method of manufacturing an information holder, wherein the information holder comprises a unisometric reflection display having a light transmissivity; and a print layer stacked on the unisometric reflection display, the unisometric reflection display includes reflectors included in a reflector holding layer of a thin film form; the reflector holding layer comprises a jagged structure of a shape of a saw blade in which convex portions each made of a first slope inclining at a first angle and a second slope inclining in a fixed direction at inclination angles different from the first angle line up on a plane of the reflector holding layer; the reflectors are provided on the second slopes; the reflector holding layer has at least three sections which are divided in a plane direction of the reflector holding layer; each of the sections includes reflectors; for each of the sections, the respective reflectors incline in the fixed direction and at a respective fixed inclination angle to a plane of the reflector holding layer; the inclination angles vary from section to section; for each of the sections, light incident from a respective first direction is reflected on a front surface of each of the respective reflectors to be inhibited from transmitting through the respective section of the reflector holding layer, for each of the sections, light incident from a respective second direction to the respective reflectors is reflected on a front surface of each of the respective reflectors and a rear surface of a respective other of the reflectors adjacent the respective reflector at a front surface side, or reflected this way a plurality of times to transmit through the reflector holding layer, the reflectors are made of a stack of an aluminum film provided on the second slopes and a magnesium fluoride film formed on the aluminum film; the aluminum film is not provided on the first slopes; the second slopes are completely covered by the aluminum film; and the first slopes are vertical to the plane of the reflector holding layer, wherein the method comprises: providing the jagged structure; depositing aluminum on a surface of the jagged structure by vacuum deposition (step A); vacuum-depositing magnesium fluoride on the surface of the jagged structure on which the aluminum was deposited (step B); soaking the jagged structure on which the aluminum and the magnesium fluoride are deposited into an alkali solution (step C) such that the stack of the aluminum film and the magnesium fluoride film formed on the aluminum film remains only on the second slopes. a print layer stacked on the unisometric reflection display, the unisometric reflection display includes reflectors included in a reflector holding layer of a thin film form;
