Provided is an excellent phthalocyanine crystal having high sensitivity and little fluctuation in sensitivity for a humidity change in a use environment and applicable to the martial for solar battery, electronic paper, electrophotographic photoreceptor, etc. An FWHM in a surface layer region at depths of from 0 to 250 nm from the upper surface is narrower than an FWHM in an inner region at depths exceeding 5 \u03bcm from the upper surface, where the FWHMs are obtained by X-ray rocking curve measurement using diffraction off a particular asymmetric plane inclined relative to the upper surface. The message software interface module is executed by the processor and displays a current electronic message on the viewing screen, filters each of the electronic messages stored in the memory device to identify one or more select messages meeting a pre-set criteria, and displays the one or more select messages on the viewing screen along with the current electronic message. Thereby, a favorable initial magnetization state in which the magnetization directions of the first and second magnetic layers are oriented antiparallel can be obtained. The at least one peel strip is positioned such that peeling off the at least one peel strip exposes the pressure-sensitive adhesive, which remains on the inner structure. The film is transparent so that the printing on the substrate can be seen through the film.
