Abstract
A laminate includes: a first laminate member; a second laminate member; and a hidden print formed by printing invisible ink between the first laminate member and the second laminate member. The hidden print is configured to absorb electromagnetic radiation outside the visible range. When irradiated with electromagnetic radiation outside a visible range that has passed through at least one of the first laminate member and the second laminate member, the hidden print absorbs the electromagnetic radiation to thereby show a sign, and, when irradiated with visible light, the hidden print does not show the sign.
