JP 2003-227221 A (Claim 1) JP 2006-124213 A (Claim 1)

  As described above, the conventional thin plate-shaped exterior material has almost no heat insulation effect, only the heat insulation effect by the heat insulation material applied to the wall surface can be obtained, and the heat insulation efficiency is very poor.

  On the other hand, according to the outer heat insulating tile and the heat insulating material composite tile, the heat insulating effect of the tile itself can be obtained together with the heat insulating effect by the heat insulating material applied to the wall surface, so that the heat insulating property of the building is greatly improved. However, these exterior materials (tiles) are expensive to manufacture and may increase the construction cost.

  Furthermore, since the surface of the exterior material of each of the conventional sheet-shaped exterior materials, outer heat insulating tiles, and heat insulating material composite tiles is a flat surface, the outer wall to which these exterior materials are attached is also a flat surface. Therefore, sunlight is directly applied to the outer wall throughout the year, but especially when the sunlight continues to hit directly in the summer, the surface of the exterior material is heated drastically and the temperature of the exterior material itself rises. It becomes difficult to fully exhibit.

  Therefore, in view of the above problems, the present inventors are relatively inexpensive, can be easily manufactured, and as a result of intensive studies to provide an exterior material that has further improved the heat insulation effect compared to conventional exterior materials, The present invention has been reached.

  That is, the gist of the L-type exterior material of the present invention is an exterior material used as a building material for a wall surface, the exterior material base having the rear surface as the wall surface attachment side, and the lower side of the exterior material base from the front side And a projecting portion extending in the lateral direction of the exterior material base, and the longitudinal cross-sectional shape is substantially L-shaped.

  Further, in such an L-shaped exterior material, the upper surface of the projecting portion is curved or inclined obliquely downward from the front surface of the exterior material base portion toward the distal end portion of the projecting portion.

  Further, in the L-shaped exterior material, a hollow portion penetrating in each lateral direction may be formed in the exterior material base portion and / or the protruding portion.

  Furthermore, in such an L-shaped exterior material, a concave groove or a ridge extending in the lateral direction of the protruding portion may be formed on the lower surface of the protruding portion.

  Further, in such an L-shaped exterior material, glossy wrinkles can be applied to the upper surface of the protruding portion and the front surface of the protruding portion.

  Furthermore, in such an L-shaped exterior material, irregularities can be formed on the upper front surface of the exterior material base.

  Further, in the L-shaped exterior material, a black coloring may be applied to the upper front surface of the exterior material base.

  Further, in such an L-shaped exterior material, a recess is formed in the upper front surface of the exterior material base, and the recess may be filled with porous ceramics for planting.

  According to the L-shaped exterior material of the present invention, sunlight can be blocked according to the irradiation angle of sunlight by the protruding portion according to the L-shaped exterior material. That is, since sunlight at a relatively large irradiation angle in summer does not directly hit the upper front surface, the exterior base of the L-type exterior material and the wall surface to which the L-type exterior material is attached Temperature rise can be suppressed. On the other hand, when the irradiation angle is relatively small in winter, the exterior material base and the wall surface can be warmed by directly applying sunlight to the upper front surface. Therefore, by applying the L-shaped exterior material of the present invention to the outer wall, the heat insulation effect of the outer wall can be easily improved without using a special heat insulating material for the wall surface or using an expensive heat insulating exterior material. Can provide buildings with outer walls that are cool in summer and warm in winter.

  Moreover, although the sunlight which directly hits the protrusion part which concerns on this invention, the said L-type exterior material is affixed on both sides of the exterior material base which concerns on the L-type exterior material of this invention. Therefore, even when the protruding portion is heated, the heat of the protruding portion is hardly transmitted to the wall surface, and the heat insulating effect is very high. Further, the projecting portion projects from the exterior material base and also has a function as a cooling fin of the L-shaped exterior material, and the heat dissipation effect of the heated L-shaped exterior material is also enhanced.

  Further, by curving or inclining the upper surface of the protruding portion according to the L-shaped exterior material of the present invention, sunlight is reflected and diffused by the upper surface, and the heat insulation effect can be further improved, and the present invention. The design of the L-shaped exterior material is also improved.

  Moreover, since the hollow part is formed in the inside of the L type exterior material of this invention, the heat insulation effect can be improved further.

  Furthermore, by forming a groove or a ridge on the lower surface of the projecting portion according to the present invention, the groove or the like functions as a water guiding means, and rainwater or the like flowing down the surface of the L-shaped exterior material of the present invention. Is transmitted to the lower surface of the projecting portion, and then uniformly and smoothly to the upper front of the exterior material base portion related to the L-type exterior material that is smoothly located below the concave grooves or ridges. It can be made to flow down, and the effect of cleaning the surface of the L-type exterior material by running water such as rain water and the cooling effect of the L-type exterior material itself can be obtained.

  Further, by applying a glossy glaze to the upper surface and the front surface of the projecting portion according to the present invention, the function of reflecting and diffusing sunlight directly hitting the upper surface and the like can be further improved, and the heat insulation effect can be further improved.

  Further, by forming irregularities on the upper front surface of the exterior material base according to the present invention, the surface area of the upper front surface is increased, and the heat insulation effect and the cooling effect are further improved, and the L-shaped exterior material of the present invention. The design is improved.

  Furthermore, by applying a black color to the upper front of the exterior material base according to the present invention, the sunlight directly hitting the upper front is actively absorbed, and the exterior material base and the exterior material base are interposed. Thus, the wall surface to which the L-shaped exterior material of the present invention is attached can be efficiently warmed.

  Further, the present invention in which the porous ceramic is planted by forming a recess in the upper front surface of the exterior material base according to the present invention and filling the recess with a porous ceramic for planting. When the L-shaped exterior material is attached to the wall surface, the wall surface is greened.

  Hereinafter, embodiments of the L-shaped exterior material of the present invention will be described with reference to the drawings. In addition, this invention is not limited to embodiment shown below.

  An L-type exterior material 10 according to the present embodiment is an exterior material used as a wall surface building material, and as shown in FIG. 1, an exterior material base 20 having a rear surface 12 as a wall surface mounting side, and an exterior material base And a protruding portion 22 that protrudes from the lower portion of 20 toward the front surface 14 side and extends in the transverse direction of the exterior material base portion 20. And the upper surface 24 of the protrusion part 22 which concerns on the L-type exterior material 10 of this embodiment is curving concavely toward the downward | lower direction, These exterior material base 20 and the protrusion part 22 are shape | molded integrally, and the vertical direction The cross-sectional shape is substantially L-shaped.

  Further, in the L-shaped exterior material 10 of the present embodiment shown in FIG. 1, a hollow portion 30 penetrating in the transverse direction is formed inside the exterior material base portion 20 and the protruding portion 22. More specifically, it is a hollow portion 30 having a substantially rectangular cross-section in the longitudinal direction, straddling the lower portion of the exterior material base 20 and the protrusion 22 according to the L-type exterior material 10, and is on the left side of the L-type exterior material 10. From the surface 16a to the right side surface 16b, it is formed in a state of penetrating the inside of the L-shaped exterior member 10 in the transverse direction of the L-shaped exterior member 10.

  Furthermore, a concave groove 32 is formed on the lower surface 28 of the protrusion 22 according to the present embodiment, extending in the lateral direction of the protrusion 22, that is, in the lateral direction of the L-shaped exterior material 10.

  FIG. 2 shows one construction example in a state where the L-shaped exterior material 10 according to the present embodiment shown in FIG. As shown in the figure, the plurality of L-shaped exterior materials 10, 10,... Are in a state where the hollow portions 30 and the recessed grooves 32 between the L-shaped exterior materials 10 adjacent in the lateral direction are communicated with each other. It is attached to the wall surface W by an adhesive material 31 such as an adhesive or mortar. In addition, the code | symbol 33 in the figure represents the joint material.

  At this time, in the L-type exterior materials 10 adjacent to each other in the vertical direction, the concave groove 32 provided in the L-type exterior material 10 located on the upper side is formed on the lower surface 28 of the protruding portion 22, and therefore located on the lower side. It will be in the state exposed ahead (front side 14 side) from the upper surface 18 of the L-type exterior material 10. In other words, when the plurality of L-shaped exterior materials 10 are attached to the wall surface W, the concave groove 32 related to the L-shaped exterior material 10 is forward (front surface 14) from the upper surface 18 of the L-shaped exterior material 10 positioned on the lower side. It is necessary to form it on the lower surface 28 of the protrusion 22. In addition, although the example of construction of a joint is shown in the figure, a some L-type exterior material may be stuck by a step joint. Even in the case of a stepping joint, the L-shaped exterior member 10 located on the upper side in a state where the hollow portions 30 and the recessed grooves 32 of the L-shaped exterior members 10 adjacent to each other in the lateral direction communicate with each other in the same manner as described above. The ditch | groove 32 which concerns on can be stuck in the state exposed ahead (front side 14 side) from the upper surface 18 of the L-type exterior material 10 located in the lower side.

  3A and 3B are side views of the construction example shown in FIG. In the same figure, the code | symbol S represents sunlight. First, as shown to Fig.3 (a), when the irradiation angle of sunlight S is large, sunlight S is irradiated with respect to the L-type exterior material 10 which concerns on this embodiment stuck on the wall surface W. FIG. Then, the sunlight S directly hits the upper surface 24 and the front surface 26 of the projecting portion 22 related to each L-shaped exterior material 10. However, the sunlight S is blocked on the upper front surface 14 of the exterior material base 20 related to the L-shaped exterior material 10 positioned on the lower side by the protruding portion 22 included in the L-shaped exterior material 10 positioned on the upper side. S does not hit directly.

  On the other hand, as shown in FIG. 3B, when the irradiation angle of the sunlight S is small, the sunlight S directly hits the upper surface 24 and the front surface 26 of the protruding portion 22 according to each L-type exterior material 10. Further, since the sunlight S is hardly blocked by the protrusion 22 provided in the L-shaped exterior material 10 located on the upper side, the sunlight is also applied to the upper front surface 14 of the exterior material base 20 related to the L-shaped exterior material 10 located on the lower side. S will be directly hit.

  Therefore, by sticking the L-shaped exterior material 10 according to the present embodiment to the wall surface W, the sunlight S at a time when summer altitude is relatively high (= the irradiation angle is large) is L-shaped exterior material 10. Therefore, the temperature rise of the exterior material base 20 and the wall surface W according to the L-type exterior material 10 can be suppressed (see FIG. 3A). On the other hand, in the winter season when the altitude is relatively low (= the irradiation angle is small), the sunlight S is directly applied to the upper front surface 14 of the exterior material base 20, and the exterior material base according to the L-type exterior material 10 is applied. 20 and the wall surface W can be warmed (see FIG. 3B). That is, by applying the L-shaped exterior material 10 according to the present embodiment to the outer wall, the heat insulation effect of the outer wall can be easily achieved without using a special heat insulating material for the wall surface W or using an expensive heat insulating exterior material. It is possible to provide buildings with outer walls that are cool in summer and warm in winter.

  In addition, the upper surface 24 and the front surface 26 of the protrusion 22 according to the L-shaped exterior member 10 of the present embodiment are directly exposed to sunlight S throughout the year regardless of the irradiation angle. However, the projecting portion 22 to which the sunlight S hits is located on the opposite side of the wall surface W (the front surface 14 side of the exterior material base 20) across the exterior material base 20 related to the L-type exterior material 10. Accordingly, even when the sunlight S in summer particularly directly hits the protruding portion 22 and the protruding portion 22 becomes hot, the heat of the protruding portion 22 is difficult to be transmitted to the wall surface W, so the heat insulating effect is very high. Further, the projecting portion 22 projects from the exterior material base portion 20 and also has a function as a cooling fin of the L-type exterior material 10, and the heat dissipation effect of the heated L-type exterior material 10 is enhanced.

  Moreover, the upper surface 24 of the protrusion part 22 which concerns on the L-type exterior material 10 of this embodiment is curving concavely toward the downward direction. Therefore, the sunlight S that hits the upper surface 24 of the protrusion 22 is reflected or diffused by the upper surface 24, and the heat insulation effect can be further improved.

  Furthermore, since the hollow part 30 is formed inside the L-shaped exterior member 10 including the protruding part 22, the heat insulation effect can be further improved.

  Further, as described above, the concave groove 32 is formed on the lower surface 28 of the protruding portion 22 according to the L-shaped exterior member 10 of the present embodiment. Accordingly, when it rains or when a separate irrigation facility is provided to irrigate the surface of the L-shaped exterior material 10, the upper front surface 14 of the exterior material base 20 related to the L-shaped exterior material 10 located on the upper side, After the rain water flowing down the upper surface 24 and the front surface 26 of the projecting portion 22 is transmitted to the lower surface 28 of the projecting portion 22, the exterior according to the L-shaped exterior material 10 that is smoothly positioned below the concave groove 32. It can flow down to the upper front 14 of the material base 20. That is, the concave groove 32 functions as a water guiding groove, and can flow down to the lower L-shaped exterior material 10 uniformly and smoothly compared to the case where the concave groove 32 is not formed. The effect of cleaning the surface of the L-shaped exterior material 10 by the above, and the cooling effect of the L-shaped exterior material 10 itself by irrigation are also obtained.

  As mentioned above, although the L-type exterior material 10 which concerns on one Embodiment of this invention was explained in full detail, the L-type exterior material of this invention is not limited to said embodiment. In particular, the length in the depth direction of the projecting portion, the height of the upper front surface of the exterior material base, the thickness of the exterior material base (length in the depth direction), the front width of the projecting portion (vertical direction) The length) is merely a design item and is not particularly limited.

  In Japan, the daytime temperature rises after the summer solstice, when the altitude of the South China is the highest, and it is the hottest time of the year from July to September. South-China altitude varies depending on the latitude of the observation site.

Here, in the L-shaped exterior material 10a shown in FIG. 4, the length of the protrusion 22 in the depth direction is X, the height of the upper front surface 14 of the exterior material base is Y, and the thickness of the exterior material base 20 (in the depth direction). When the length (Z) is Z, the width (length in the vertical direction) of the front surface 26 of the protrusion 22 is T, and the irradiation angle (south / central altitude) of the sunlight S1 is θ, A relationship is established.
X = Y / tan θ (Equation 1)

  For example, when looking at Sapporo, the summer altitude in the south is about 70 to 45 degrees. Therefore, when the thickness Z of the exterior material base 20 and the width T of the front surface 26 of the protrusion 22 are the same and θ = 45 degrees, the height Y of the upper front surface 14 of the exterior material base 20 is set to an arbitrary length. By setting, the length X of the protrusion 22 in the depth direction can be determined. In the L-shaped exterior material 10a shown in FIG. 4, the length X of the protrusion 22 in the depth direction is set so that the irradiation angle θ of the sunlight S1 is 45 degrees. Accordingly, the sunlight S1 having an irradiation angle θ of 45 degrees or more is blocked by the protruding portion 22 related to the L-type exterior material 10a located on the upper side, and thus the upper front surface 14 related to the L-type exterior material 10a located on the lower side. There is no direct hit, and the heat insulation effect can be enhanced. On the other hand, since the irradiation angle θ of the sunlight S1 in winter is less than about 45 degrees (see Table 1), the sunlight S1 is not blocked by the protruding portion 22 related to the L-shaped exterior material 10a located on the upper side, and the exterior The sunlight S1 is also directly applied to the upper front surface 14 of the material base 20, and the exterior material base 20 and the wall surface W can be warmed.

  Further, the protruding portion 22 related to the L-shaped exterior material 10a of the present embodiment also has a heat dissipation function as a cooling fin, a reflection function of sunlight S1, and a diffusion function, like the protruding portion 22 related to the L-shaped exterior material 10. ing.

  The design example for determining the length X in the depth direction of the protrusion 22 according to the L-shaped exterior material 10a of the present embodiment has been described above in detail. According to the L-shaped exterior material 10a, the sunlight S1 can be blocked by the protrusion 22 if the irradiation angle θ of the sunlight S1 is 45 degrees or more. However, as shown in [Table 1], in areas such as Tokyo and Osaka, the irradiation angle (south and middle altitude) θ exceeds 50 degrees even in the autumn. When the L-shaped exterior material 10a is used in these areas, the period in which the sunlight S1 is blocked by the protrusions 22 becomes longer, and the sunlight S1 at a time when the solar light S1 begins to get cold is positively seen from the upper front of the exterior material base 20 14 cannot be applied directly.

  That is, in the L-type exterior material of the present invention, the length X in the depth direction of the protruding portion is attached to the wall surface W of the floor area and the direction of the wall surface W where the L-type exterior material is used. It can be set in consideration of the above. And when actually sticking the L-type exterior material of the present invention to the wall surface W of the building, for example, the L-type exterior material having a short length X in the depth direction of the protruding portion is attached to the south wall surface W. In addition, by sticking an L-shaped exterior material having a long X to the west wall W, the solar light having a large daytime irradiation angle θ and the sunlight having a small evening irradiation angle θ are blocked by the protrusions, respectively. It is possible to further enhance the heat insulation effect.

  Further, in the L-type exterior material 10a of the present embodiment, the thickness Z of the exterior material base 20 and the width T of the front surface 26 of the protrusion 22 are designed to be the same. For example, the L-type exterior shown in FIG. As in the material 10b, the thickness Z of the exterior material base 20 and the width T of the front surface 26 of the protrusion 22 may be different. In the L-shaped exterior material 10b of the present embodiment, the irradiation angle (South / South altitude) θ is set to 60 degrees, but the width T of the front surface 26 of the protrusion 22 is made smaller than the thickness Z of the exterior material base 20. Therefore, the radius of curvature of the upper surface 24 of the curved protrusion 22 is made smaller than that of an L-shaped exterior material (not shown) in which the thickness Z of the exterior material base 20 and the width T of the front surface 26 of the protrusion 22 are the same. It is possible to improve the reflection and diffusion functions of sunlight S2.

  Further, the shape of the protruding portion according to the L-shaped exterior material of the present invention is not particularly limited, and the upper edge portion 27a of the front surface 26 according to the protruding portion 22 is formed as in the L-shaped exterior material 10c shown in FIG. The lower edge 27b may be curved, or may be chamfered (not shown). Furthermore, like the L-shaped exterior material 10d shown in FIG. 6B, the upper edge portion 27a of the front surface 26 (= the front end portion of the protrusion portion 22) of the protrusion 22 is curved, and the front surface 26 and the lower surface The aspect where 28 curved continuously may be sufficient. In particular, by making the shape of the protruding portion according to the present invention the shape of the protruding portion 22 according to the L-shaped exterior material 10d, rainwater can be smoothly transferred into the concave groove 32 as compared with the protruding portion 22 according to other embodiments. Can lead to.

  Moreover, although the upper surface 24 of the protrusion part 22 which concerns on the said various embodiment is all curved in the concave shape toward the downward direction, you may make it curve in a convex shape toward the upward direction (not shown). Alternatively, like the L-shaped exterior member 10e shown in FIG. 7, the upper surface 24 of the projecting portion 22 extends from the front surface 14 of the exterior material base portion 20 to the tip end portion of the projecting portion 22 (= the upper edge of the front surface 26 related to the projecting portion 22). An aspect inclined obliquely downward toward the portion 27a) may be employed. Even if it is which aspect, the sunlight which directly hits the upper surface 24 which concerns on the protrusion part 22 can be reflected and diffused, and the heat insulation function with which the L-type exterior material 10e is provided can be improved. In addition, the aspect which inclined the upper surface 24 of the protrusion part 22 like the L-type exterior material 10e shown in FIG. 7 is more preferable when improving the reflection and the spreading | diffusion function of sunlight.

  Further, as in the L-shaped exterior material 10f shown in FIG. 8, the upper surface 24 of the protrusion 22 may be a flat surface. That is, the upper surface 24 of the projecting portion 22 and the front surface 14 of the exterior material base portion 20 according to the L-type exterior material 10f shown in the same figure form a right angle, and the longitudinal sectional shape of the L-type exterior material 10f is L-shaped. The aspect which makes | forms may be sufficient. Also by sticking the L-type exterior material 10f to the wall surface W, the sunlight S at a time when the summer height is relatively high (= the irradiation angle is large) is the exterior material base part related to the L-type exterior material 10f. Since it does not directly hit the upper front surface 14 of 20, the temperature rise of the exterior material base 20 and the wall surface W can be suppressed. On the other hand, in the winter season when the altitude is relatively low (the irradiation angle is small), sunlight S is directly applied to the upper front surface 14 of the exterior material base 20 to warm the exterior material base 20 and the wall surface W. it can.

  In addition, the projecting portion 22 related to the L-shaped exterior material 10f also has a function as a cooling fin, similarly to the L-shaped exterior material 10 according to the above-described embodiment, and further, sunlight that hits the upper surface 24 of the projecting portion 22. It is also possible to improve the heat insulation effect by reflecting or diffusing S.

  As mentioned above, although various embodiment of the L-type exterior material of this invention was explained in full detail, the L-type exterior material of this invention can be implemented also in other embodiment.

  In the L-shaped exterior materials 10, 10a to 10f according to the above-described embodiment, the hollow portion 30 is formed in order to enhance the heat insulating effect. Thus, the L-shaped exterior material of the present invention has a hollow portion. It is more preferable. In addition, the formation position, longitudinal direction cross-sectional shape, etc. of the hollow part formed in the L-shaped exterior material of the present invention are not limited to the hollow part 30 according to the above embodiment, and are shown in FIGS. It is also possible to form the hollow portions of various aspects as described above. Specifically, as shown in FIG. 5A, the hollow portion 30 a having a circular longitudinal cross-sectional shape is formed in the lower portion of the exterior material base 20 and the protrusion 22, respectively, in the transverse direction of the L-type exterior material 10. It may be formed in a state of penetrating through. Alternatively, as shown in FIG. 4B, only the exterior material base 20 is formed with a hollow portion 30b having a substantially rectangular cross-sectional shape in the longitudinal direction penetrating in the lateral direction of the L-shaped exterior material 10. May be. Furthermore, as shown in FIG. 3C, the longitudinal cross-sectional shape of each of the hollows has a substantially rectangular shape at the position straddling the lower part of the exterior material base 20 and the protrusion 22 and the upper part of the exterior material base 20. The portions 30 and 30b may be formed in a state of penetrating in the transverse direction of the L-shaped exterior material 10. Furthermore, although these hollow parts 30, 30a, 30b are all formed in a state of penetrating the inside of the L-shaped exterior member 10 in the lateral direction, both ends of the hollow part 30 or the like, that is, left and right of the L-shaped exterior member 10 are formed. The openings formed in the side surfaces 16a and 16b may be closed.

  Further, the position of the concave groove 32 formed in the L-shaped exterior material 10 or the like according to the above embodiment is not particularly limited as long as it is the lower surface 28 of the protruding portion 22, and as shown in FIG. The lower surface 28 of the portion 22 may be formed at a position biased toward the front surface 26 side of the protruding portion 22. Further, what is formed on the lower surface 28 of the protrusion 22 is not limited to the concave groove 32. For example, as shown in FIG. 10B, a ridge 34 extending in the lateral direction of the protruding portion 22, that is, in the lateral direction of the L-shaped exterior member 10 may be formed on the lower surface 28 of the protruding portion 22. By forming such ridges 34, rainwater or the like flowing down the surface of the L-shaped exterior member 10 is placed on the lower side from the lower surface 28 of the projecting portion 22 of the upper L-shaped exterior member 10. It is possible to smoothly flow down to the upper front surface 14 of the exterior material base 20 related to the exterior material 10. Further, when the L-type exterior material 10 is adhered to the wall surface W, the protrusion 34 is adhered to the upper front surface 14 of the exterior material base 20 related to the L-type exterior material 10 located on the lower side. This facilitates the positioning of the L-shaped exterior material 10 and can improve the efficiency of the sticking operation.

  As mentioned above, although various embodiment which concerns on the L-type exterior material of this invention was explained in full detail, this invention is not limited to said embodiment. For example, it is preferable that the upper surface and the front surface of the projecting portion according to the L-shaped exterior material of the present invention are glazed. Like the L-shaped exterior material 10g shown in FIG. 11A, the sun directly hits the upper surface 24 and the like of the projecting portion 22 by applying the glossy glazing 29 to the upper surface 24 and the front surface 26 of the projecting portion 22. The light reflection and diffusion functions are further improved, and the heat insulation effect can be further improved.

  Moreover, although the upper front 14 of the exterior material base 20 according to the various embodiments described above is flat, the upper part of the exterior material base 20 is similar to the L-type exterior material 10h shown in FIG. Concavities and convexities 15 may be formed on the front surface 14. The unevenness 15 shown in the figure is formed by providing a plurality of concave grooves 35 in the upper front surface 14. By forming such irregularities 15, the surface area of the upper front surface 14 is increased, the heat insulation effect and the cooling effect are further improved, and the design of the L-shaped exterior material is also improved. In addition, it does not specifically limit as a method of forming the unevenness | corrugation 15 in the upper front surface 14, For example, the unevenness | corrugation 15 may be formed by a scratch etc. FIG. Moreover, the formation direction of the unevenness | corrugation 15 is not limited, The vertical direction and the diagonal direction may be sufficient besides the horizontal direction shown in figure. Furthermore, the unevenness | corrugation 15 may be formed by making the upper front 14 into a wave surface or a streak surface.

  Moreover, it is preferable that the upper front 14 of the exterior material base 20 according to the above-described various embodiments is provided with a black color (not shown).
