Is set. For example, when the length of the rhombic horizontal diagonal line X composed of the contours of the installation surfaces of the concave portions 35 and the convex portions 36 is 0.8 mm, the length of the vertical diagonal line Y is set to 0.4 mm. When the length of the horizontal diagonal line X is 1.0 mm, the length of the vertical diagonal line Y is set to 0.5 mm. Moreover, the height of the convex part 36 is installed in 50-80 micrometers like the convex part 33, for example. When the concave portion 35 and the convex portion 36 are formed with the above dimensions, the aesthetic appearance of the digital still camera 1 is improved and the frictional resistance of the surface of the outer casing front forming portion 41 is increased. In particular, when the user's hand is attached to the main body of the digital still camera 1, the user's finger can be easily locked to the plurality of convex portions 36 that are continuously arranged, and the digital still camera can be surely secured during shooting. 1 becomes easy to hold. The convex portion 36 is formed in a triangular prism shape, but may be formed in a triangular pyramid shape.

A plurality of mode display portions 39 indicating the shooting mode are formed on the end surface 37 of the mode dial 14. The mode display unit 39 is disposed along the periphery of the end surface 37. The side surface 38 of the mode dial 14 is provided with an uneven pattern 40. The concavo-convex pattern 40 is a pattern made of concavo-convex, and is formed by a known etching method. Examples of the concavo-convex pattern 40 include arabesque patterns and laurel patterns made of concavo-convex patterns.

Since they are continuously arranged, the beauty of the digital still camera 1 is improved and a high-class feeling is exhibited.

  Further, the frictional resistance of the surface of the outer casing front forming portion 41 is increased, and the digital still camera 1 can be reliably held only by placing a hand on the main body of the digital still camera 1 during photographing. Therefore, the digital still camera 1 can be reliably operated and a good image can be taken.

  In particular, when the etching pattern is formed as the concave and convex patterns 31 and 34, the user's finger of the digital still camera 1 can be easily locked to the convex portions 33 and 36 that are continuously arranged, so that The digital still camera 1 can be reliably held and operated.

  Then, the side surface 38 of the mode dial 14 of the digital still camera 1 is etched to form the concavo-convex pattern 40, thereby improving the aesthetics of the mode dial 14. Furthermore, the high-class feeling of the digital still camera 1 is increased. Further, the frictional resistance on the surface of the side surface 38 of the mode dial 14 is increased, and the operation of the mode dial 14 can be performed reliably.
