Abstract: An ion exchange membrane, a method for producing an ion exchange membrane, and an electrolyzer that enable a reduction in the electrolytic voltage when subjected to electrolysis are provided which have small influence of impurities in the electrolyte on electrolysis performance, and exert stable electrolysis performance. An ion exchange membrane includes a membrane main body containing a fluorine-containing polymer having an ion exchange group; and a coating layer arranged on at least one face of the membrane main body. The coating layer includes inorganic particles and a binder, a mass ratio of the binder to the total mass of the inorganic particles and the binder in the coating layer is 0.3 or more and 0.9 or less, and a coverage of the membrane main body with the coating layer is 50% or more.

Abstract: Disclosed is an edible object marking apparatus (1) wherein a carrier means (20) successively conveys an edible object to a detecting means (210), a marking means (220), and a marking inspecting means (230) while holding the edible object, wherein the detecting means (210) captures an image of the edible object to acquire orientational data indicating the orientation of the edible object, the marking means (220) forms a pre-set marking pattern in accordance with the orientation of the edible object based on the orientational data, and the marking inspecting means (230) captures an image of the edible object, extracts marking pattern data, compares the marking pattern data with pre-set reference pattern data based on the orientational data acquired by the detecting means (210) to thereby inspect marking accuracy. This edible object marking apparatus makes it possible to promptly and easily obtain edible objects provided with an accurate marking.
