Abstract: The adhesive sheet includes an adhesive layer (A1L) in solid form at 18° C., wherein the adhesive layer (A1L) contains an epoxy resin, at least one surface of the adhesive layer (A1L) has a tackiness agent region (A2R) formed by partially providing a tackiness agent (A2), and a region where the tackiness agent region (A2R) is not formed on the surface is an adhesive-layer-exposed region (A1LR) where a surface of the adhesive layer (A1L) is exposed. This adhesive sheet has excellent temporary fixability at the time of sticking (a characteristic that exhibits the tackiness force necessary for temporary fixation) and adhesive force after heat curing.

Abstract: A camera system includes: a digital camera; and a key device configured as a unit separate from the digital camera. The digital camera includes a control device that sets a lock mode for encrypting image data and recording the encrypted image data into a recording medium and clears the lock mode in response to a lock release signal input via the key device.

Abstract: The present invention provides a stretched laminate film with oxygen-gas barrier properties which includes a layer (a) formed from a composition of a polycarboxylate-based polymer (A) and a plasticizer (B), a layer (c) containing a multivalent metal compound (C) and a layer (b) formed from a thermoplastic resin, which film includes at least one layer forming unit where the layer (a) and the layer (c) are adjacent to each other, and in which film at least the layer (a) and the layer (b) are stretched with a surface stretch ratio of 1.1 to 100. By means of carrying out an applying step and a stretching step according to a production method of the present invention, the layer formed from the polycarboxylate-based polymer including the plasticizer can be made thinner, although making the layer thinner has been difficult to achieve as long as only the application is carried out.
