Abstract: Provided is a curable composition having excellent workability and being capable of forming a cured product having excellent heat resistance. The curable composition of the present invention includes a compound represented by Formula (1) below and a solvent: In Formula (1) below, R1 and R2 each represent a curable functional group, and D1 and D2 each represent a single bond or a linking group. L represents a divalent group having a repeating unit containing a structure represented by Formula (I) below and a structure represented by Formula (II) below. In Formula (I) and Formula (II) below, Ar1 to Ar3 each represent a group in which two hydrogen atoms are removed from an aromatic ring structure or a group in which two hydrogen atoms are removed from a structure in which two or more aromatic rings are bonded through a single bond or a linking group. X represents —CO—, —S—, or —SO2—, and Y represents —S—, —SO2—, —O—, —CO—, —COO—, or —CONH—. n represents an integer of 0 or greater.

Abstract: An electronic device can be inserted into a pocket formed with a main cover through between a side cover and the main cover. A part of the electronic device where an operating stick is formed can be stored in a flap formed with the side cover. The upper end of the flap rim of the side cover is positioned further away from the center line C1 of the case than the lower end is. The pocket rim of the main cover gets closer to the center line C1 of the case as it goes from the upper end to the lower end. According to a case including the main cover and the side cover, insertion/removal work of the electronic device can be facilitated, undesired exposure of the electronic device can be prevented, and a load applied to the operating stick can be readily reduced.
