A two-dimensional code that is capable of suppressing unnecessary code detection processes related to detection of a code area is provided. Among outer edges of a rectangular code area, a first edge that is composed of a plurality of types of cells arrayed in a single row is configured such that a specific pattern that is composed of an array of two or more differing cells is repeated in at least an intermediate portion. A second edge composed of the plurality of types of cells arrayed in a row such as to oppose the first edge is configured such that the specific pattern is repeated in at least an intermediate portion.

Two-dimensional code composed of a plurality of types of cells

A portable information code reading apparatus includes an image unit imaging an information code, a processing unit encoding the information code imaged by the imaging unit, a case that holds the imaging unit and the processing unit. An attaching member is produced integrally with the case or produced as a separate member from the case. The attaching member is used to hook the case on a user's ear.
