  Here, the outer edge portion 11b is a joint portion with the rear cover 12, and as shown in FIGS. 1 to 4, the surface is carbonized together with the fitting concave portion 11c to form a carbonized layer Lc. The front cover 11 has a carbonized layer Lc formed on the outer edge portion 11b, so that the expansion and contraction of the outer edge portion 11b due to moisture absorption and discharge is fixed. However, since the outer edge portion 11b only has its expansion and contraction fixed by carbonization, it is possible to absorb and discharge moisture. The same applies to the outer edge portion 12c of the rear cover 12. Here, in FIG. 3, the lens barrier 13 is omitted to show the internal structure of the exterior material 10.

  The rear cover 12 is provided with a mounting opening 12a (see FIG. 3) for attaching the liquid crystal monitor 16 at a substantially central portion, and a lid 12b that covers the connection opening for connecting / disconnecting the connection cable connected to the connection terminal 14e at the side.

As shown in FIGS. 5 and 6, the rear cover 12 is formed with a semicircular cutout 12 e that forms a through hole through which the dial switch 17 is inserted at the upper edge.

  The lens barrier 13 partially covers the front portion of the front cover 11 and is slidably attached to the front cover 11 in the left-right direction. As shown in FIG. 2, when the lens barrier 13 is moved toward the dial switch 17, the photographing mode is turned on, and the imaging lens 15 protrudes from the lens hole 11a. On the other hand, when the lens barrier 13 is returned to the center shown in FIG. 1, the photographing mode is turned off, and the imaging lens 15 is accommodated in the exterior member 10 from the lens hole 11a. As shown in FIG. 4, the lens barrier 13 is provided with sliding pieces 13 a that engage and slide with guide rails 11 e provided at the upper and lower parts of the front cover 11 at the upper and lower edges.

  As shown in FIG. 3, the internal mechanism 14 includes an imaging device 14a such as a CCD, a driving circuit 14b for the imaging device 14a, a driving circuit 14c for the liquid crystal monitor 16, a recording device 14d for an image recording medium, and a connection terminal for an external personal computer. 14e and the like. Here, the internal mechanism 14 is mounted on a substrate 18 (see FIG. 5) described later.

  As shown in FIGS. 1 and 2, the dial switch 17 is a rotating member that also serves as a switch that switches in a shooting mode such as manual, auto, and self-timer by rotating in the direction of the arrow, as shown in FIGS. It is provided in the upper part of the exterior material 10. As shown in FIG. 5, the dial switch 17 is provided with an operation dial 17b at the upper part of the shaft part 17a and an engaging part 17c at the lower part. The dial switch 17 is engaged with a movable contact piece 19 provided inside the exterior member 10. That is, the movable contact piece 19 has an engagement hole 19b formed in the main body 19a and a plurality of switching contact pieces 19c. By engaging the engagement portion 17c with the engagement hole 19b, the dial switch 17 is rotated. At this time, the plurality of switching contact pieces 19c contact the corresponding conductive circuits 18a of the plurality of conductive circuits 18a formed on the substrate 18, thereby switching the digital camera 1 to various photographing modes.

  In the digital camera 1 configured as described above, the internal mechanism 14 and the imaging lens 15 are housed in the exterior material 10, the dial switch 17 and the movable contact piece 19 are engaged, and the lens barrier 13 is attached. The front cover 11 is assembled with the rear cover 12 for assembly.

  At this time, in the digital camera 1, as shown in FIGS. 1 to 4, the carbonized layer Lc is formed on the surfaces of the outer edges 11 b and 12 c of the front cover 11 and the rear cover 12. For this reason, in the digital camera 1, the carbonized layer Lc of the outer edge portions 11b and 12c is harder and harder to peel than the carbonized wood, and only the outer edge portions 11b and 12c are carbonized. The front cover 11 and the rear cover 12 are less likely to be deformed than when carbonized.

  In addition, in the digital camera 1, the carbonized layer Lc is formed on the outer edge portions 11 b and 12 c which are joint portions between the front cover 11 and the rear cover 12. Therefore, in the digital camera 1, the odor generated from the electronic components such as the image pickup device 14a housed inside is adsorbed by the carbonized layer Lc and does not leak to the outside and give the user unpleasant feeling, so that the usability is improved. Moreover, since the carbonized layer Lc absorbs moisture entering from the outside, the deterioration of the electronic components stored while the inside is maintained in a dry state is suppressed.

  Here, the carbonized layer Lc of the outer edge portions 11b and 12c is formed by, for example, a burner flame, a shochu, or a laser beam. FIG. 7 shows, as an example, a method of forming a carbonized layer Lc on the outer edge portion 11b of the front cover 11 with shochu. The shochu cake 20 includes a handle portion 20a for holding and a heating portion 20b having a shape corresponding to the outer edge portion 11b. In order to form the carbonized layer Lc, the heating portion 20b may be moved along the outer edge portion 11b at a constant speed while the heating portion 20b heated to an appropriate temperature is applied to the outer edge portion 11b.

  In addition, as shown in FIG. 3, when the digital camera 1 carbonizes the lens hole 11 a penetrating the exterior material 10 in the thickness direction and the peripheral surface of the mounting opening 12 a to form the carbonized layer Lc, moisture and odor are generated. The carbonized layer Lc in the lens hole 11a and the mounting opening 12a is also adsorbed. As a result, in the digital camera 1, leakage of odor to the outside through the lens hole 11a and the mounting opening 12a and intrusion of moisture from the outside are suppressed, and the moisture and odor adsorption effect is further improved. Further, as shown in FIG. 6, the notches 11d and 12e forming the through holes for inserting the dial switch 17 adsorb moisture and odor by the carbonized layer Lc when the peripheral surface is carbonized to form the carbonized layer Lc. In addition, leakage of odor to the outside through the notches 11d and 12e and intrusion of moisture from the outside are suppressed.

  In the above embodiment, the case of a digital camera as an electronic device has been described. However, as long as the electronic device of the present invention has an exterior material that can be assembled by joining at least two components made of compressed wood at the joint, the mobile device (mainly a mobile phone), an IC recorder, and a PDA Mobile electronic devices such as portable televisions, portable radios, and remote controls for various home appliances are targeted.
