Lamps, as well as those suitable for wire materials. In particular, it is a wire having high strength and excellent in weld oxidizability and electrical conductivity.先前 [Prior Art] A light source is used for various light sources such as a light source for a document illumination of an image scanner or a liquid crystal display device such as a liquid crystal display for a computer or a liquid crystal display device. As shown in FIG. 1 , in general, a cold cathode fluorescent lamp is provided with a phosphor tube 11 having a phosphor layer 11 at an inner wall surface and a glass tube having a rare gas and mercury, and a pair disposed in the glass bottle. The electrode portion 13 and the lead portion 14 that is electrically connected to the electrode portion 13 are supplied to the electrode portion 13. There is also a cold cathode fluorescent wire portion 14 of a mercury-free gas sealed in the glass tube 12, which is provided with an inner wire 1 4 i in which one end is joined, and another main wire which is bonded to the inner wire 1 4 i The outer lead 1 4 is disposed outside the glass tube 1 2 . Since the inside of the glass tube 12 is fixed to the glass portion 15 in the glass tube 12 by the end portion of the glass tube 12, the material is adjusted to have a coefficient of thermal expansion coefficient with the glass. The wire of the electrode portion line constitutes the strength and resistance of the above-mentioned wire as a person (the liquid crystal display has a cold cathode fluorescent lamp 1 〇, representative, and is enclosed in the glass tube 12, and is used to have only a rare lamp tube. The outer end of the part 13 and the wire 14i, sealed and electrically, in the material of the material is slightly the same as the thermal expansion coefficient of -5 - 201101366, for example, using Kovar (Κ 〇 v ), etc. On the outer conductor 1 4 〇 For example, a wire having a copper coating (about 20% by mass of the core material) in the outer periphery of the core material made of the alloy of 58 % N i - 4 2 % F e is used (refer to Patent Documents 1 and 2). Typically, a Dumet wire or the like is used. The outer circumference of the outer wire 14 is coated with a solder 20' and is connected to a terminal (not shown) via the terminal and the wire. The portion 14 is supplied with electric power to the electrode portion 丨3. [Patent Document] [Patent Document 1] Japanese Laid-Open Patent Publication No. 2007-173197 [Patent Document 2] Japanese Patent Laid-Open Publication No. Hei 2 0 0 8 - 1 2 3 7 2 2 [Invention] [Invented] In recent years, it is expected that the liquid crystal display device and the like will be reduced in size and power consumption. In order to meet this requirement, it is reviewed that the glass tube of the cold cathode fluorescent lamp is lightened, or In order to reduce the number of cold cathode fluorescent lamps installed in one liquid crystal display or the like, the glass tube or the electrode portion is increased in diameter. The above-mentioned long strip and large diameter are cooled. The weight of the cathode fluorescent lamp tube tends to increase. Due to such a large weight, the load applied to the wire portion, particularly at the outer wire, or the vibration system becomes large, so at the outer wire, It is required to have high strength. In particular, the outer conductor 'sends heat due to being welded to the inner conductor, or when the glass portion is fused to the inner conductor, or -6 - 201101366 When the glass tube is used as a heat when sealing, etc. There is a tendency to reduce the degree. Therefore, it is desirable to develop a high-strength outer lead even when subjected to such a heat history. Further, due to the increase in the above weight, the load applied to the lead portion or In the case where the vibration or the like is large, the strength (welding strength) of the welded portion between the outer lead and the inner lead is low, and the welded portion is broken and the two are separated. Therefore, if it is considered In the case of long strips and large diameters, it is desirable to be able to increase the welding strength of the wire portion compared to the prior art. 'Additionally, due to the increase in the above weight, the load or vibration applied to the wire portion The system becomes large, and as a result, if the wettability between the outer lead and the solder is low, the lead portion and the terminal are separated. Therefore, in consideration of the strip length and the large diameter, it is desirable to be able to improve the wettability between the outer lead and the solder as compared with the prior art. Further, by reducing the number of tubes of the cold cathode fluorescent lamp () mounted on a liquid crystal display or the like, the cost can be reduced. However, since the number of roots is reduced, the current flowing through one cold cathode fluorescent lamp tube is increased in order to maintain a specific brightness. Therefore, it is desirable to have resistance at the wire. Live the electrical conductivity or thermal conductivity of large currents. Accordingly, it is a primary object of the present invention to provide a wire having high strength, high welding strength, excellent wettability with solder, and high electrical conductivity and thermal conductivity. Further, another object of the present invention is to provide a lead member including the lead wire, an electrode member including the lead member, a cold cathode 201101366 fluorescent tube including the electrode member, and a wire suitable for the wire. Line material. [Means for Solving the Problem] The present inventors have reviewed various compositions for the development of a wire having high strength and high strength of the welded portion and excellent wettability between solders. As a result, knowledge has been obtained that a wire having a local strength can be obtained by adding nickel (Ni) as a base material and adding a specific halogen in a specific range. In addition, it is also known that the "nickel alloy containing the specific element described above" is excellent in oxidation resistance, and therefore it is difficult to form an oxide film and the oxide film is small. As a result, the wettability with the solder is improved. 'There is also the knowledge that the nickel alloy containing the above specific elements does not become too large because of the electrical specific resistance of the material. Therefore, the electrical conductivity is excellent, even if it is In the case of a large current flowing, the heat generation of the wire is also small, and it is possible to suppress the failure of the vicinity of the electrode portion of the cold cathode fluorescent lamp caused by the heat generation. Further, knowledge is obtained that, by controlling the carbon (C) within a specific range, the wettability is improved by the decrease in the surface tension of the wire during welding, and as a result, It can be welded to the inner wire in a strong manner, and the welding strength can be improved. The present invention is based on the knowledge of such knowledge. The lead wire of the present invention is a lead wire for supplying electric power to the electrode portion of the cold cathode fluorescent lamp tube, and is characterized in that it is composed of a nickel alloy, and the nickel alloy is 0.000 1 mass% or more. 〇3质量% or less -8 - 201101366 Including c, and a total of 1.0% by mass or more and 9.0% by mass or less, including one or more elements selected from Mn, Si, and Cr, and the residue It is made up of Ni and unavoidable impurities. Further, the wire of the present invention is characterized in that it is composed of a nickel alloy having a mass of 〇·〇〇〇. In the above-mentioned content of 3% by mass or less, C is contained, and the content of one or more selected from Mn, Si, and Cr is contained in a total amount of 1.0% by mass or more and 9.0% by mass or less, and the residue is contained. In order to be made of Ni and unavoidable impurities, the strand is suitable for use in the material of the wire of the present invention described above. The lead wire of the present invention having the above-described configuration and the strand of the present invention are formed by a nickel alloy containing a specific element in a specific range, whereby the element can be solidified by solid solution strengthening. It has high strength. Therefore, the wire of the present invention or the wire formed by the wire material of the present invention can be maintained at a high strength even if it is softened by heat during welding or heat during melting of the glass. Further, the lead wire of the present invention and the twisted wire material of the present invention are composed of a nickel alloy mainly composed of nickel and containing a specific element, whereby the film is excellent in oxidation resistance. It is possible to reduce the formation of the oxide film, which is excellent in wettability with solder. Further, the wire of the present invention and the strand of the present invention are contained by relatively reducing c, and the dissolved oxygen of the molten pool (molten ρ ο ο 1 ) is increased at the time of welding, and the wire is lowered. The surface tension and the improvement of the wetting property can be strongly welded by this. The welded portion of the wire of the present invention or the wire formed by the wire of the present invention and the inner wire are provided with high strength. Further, the wire of the present invention or the wire made of the wire material of the present invention of the -9-201101366 can be obtained by setting the main body of the constituent material to nickel: (1) the electrical conductivity system Because it is excellent, it can be used as a power supply line, and (2) because the thermal conductivity is excellent. Therefore, even when a large current flows, the heat generated in the vicinity of the electrode portion can be reduced. The decrease in the brightness of the cold cathode fluorescent lamp caused by the temperature rise or the thermal deterioration of the element around the electrode portion is prevented. Further, the wire of the present invention is excellent in various properties such as mechanical properties or wettability between solders, wettability at the time of welding, electrical properties, and the like as described above. The minimum level of characteristics is also high. By using such a wire of the present invention or the wire material of the present invention, it is possible to stably produce a cold cathode fluorescent lamp having sufficiently good characteristics even if there is a slight variation in characteristics. Form the part. Therefore, even when the manufacturing process (welding, glass melting, welding, etc.) is automated in order to improve the productivity of the cold cathode fluorescent lamp or its components, it is expected to be able to manufacture. A product with high reliability. [Effect of the Invention] The wire of the present invention is high in strength and high in electrical conductivity, and is excellent in wettability between solder and solder, and the strength of the welded portion is also high. [Embodiment] Hereinafter, the present invention will be described in more detail. In addition, the proportion of the dimensions of the drawings is not necessarily consistent with those described. -10- 201101366 [Wire, wire material] (composition) The nickel alloy constituting the wire of the present invention and the wire material of the present invention is characterized by the fact that the content of C (carbon) is relatively small as one of the characteristics. The C system is 0.0001% by mass or more and 0.03% by mass or less. Commercially available pure Ni (99% by mass or more is Ni), and since many products contain 0.10% by mass or more of C, if the commercially available Ni is directly used as the raw material 0, it may become the content of c. The amount exceeds 0.03 mass% of the nickel alloy. On the other hand, if the content of c in the nickel alloy exceeds 0.03 mass%, the strength is increased by the increase of C, but conversely, the wettability at the time of welding is low, and the strength of the welded portion is low. The reason why the above wetting property is low is conceivable because if the content of C is increased, it is easy to combine with dissolved oxygen in the fusion pool and produce CO (carbon monoxide) or carbon dioxide during welding. Such a gas containing carbon causes a decrease in the amount of dissolved oxygen due to the generation of the gas, and as a result, the surface tension of the guide wire becomes high. Further, in the vicinity of the joint portion between the outer lead and the inner lead, in the case where the glass is melted or the like, the glass may be covered. If the carbon-containing gas is generated in the case where the glass is fused, the inside of the glass portion (near the lead portion) in the cold cathode fluorescent lamp tube may have bubbles of the gas. . The air bubbles are at the end of the sealed glass portion, and are the starting point of the crack, and the gas such as a rare gas enclosed in the glass tube is leaked through the crack due to the propagation of the crack. To the outside of the glass tube, it may be the reason for shortening the life of the cold cathode fluorescent lamp. Therefore, in the present invention, the upper limit ′ of the content of c is set to 0.03 mass%. On the other hand, if the content of c is too small, it is conceivable that 'the oxygen in the atmosphere is taken into the nickel alloy during the welding, and the oxidation between the oxygen and the additive element in the nickel alloy is precipitated. The object' reduces the strength of the welded portion. Therefore, in the present invention, the lower limit of the content of C is set to 0.00 0 1% by mass. A more desirable content of C is 0.005 mass% or more and 0.01 mass% or less. In order to make the content of c into the above range, a method of using a material having a small content of C in the raw material or adjusting (reducing) by refining may be mentioned. The nickel alloy constituting the wire of the present invention and the wire material of the present invention is contained in an amount of 1.0% by mass or more and 9.0% by mass or less based on the total of one or more elements selected from the group consisting of Μη, Si, and Cr as an additive element. As one of the features. The more desirable total content is 2.0% by mass or more and 5.0% by mass or less. The content of the additive element can be adjusted to the above range by adjusting the amount of the element to be added as a raw material. By including Μη, the following effects can be obtained: (1) the oxidation resistance and the strength can be improved; and (2) when the burner is used in the glass fusion or the like, the combustion gas can be used. The embrittlement of the material caused by the sulfur component is reduced. The ideal content of Μη is 〇. 〇 i mass% or more and 4.0 mass% or less. If it is less than 0.01% by mass, it is difficult to sufficiently improve the strength or oxidation resistance, and if it exceeds 4.0% by mass, electrical conductivity or thermal conductivity is likely to be lowered. -12- 201101366 It is possible to increase the strength by containing Si or Cr. In particular, if one or more elements containing Si and Cr are used, the oxidation resistance is higher than when only Μη is contained. Excellent tendency. Therefore, it is preferable to include at least one element of Si and Cr, or an element containing at least one of Si and Cr, and Μη, and it is preferable to include three elements. An ideal total content of one or more elements of Si and Cr is 0.01% by mass or more and 6.0% by mass or less. If it is less than 〇1% by mass, it is difficult to sufficiently increase the strength or oxidation resistance, and if it exceeds 6.0% by mass, electrical conductivity or thermal conductivity is likely to be lowered. In addition, as the additive element, one or more elements selected from Mg, A1, and Ti may be contained in an amount of 0.001% by mass or more and 2.0% by mass or less. These elements function as the effect enhancing elements of Mn, Si, and Cr described above. Specifically, by including Mg, Al, and Ti, it is possible to suppress the enthalpy of oxidation of Μη, Si, and Cr at the time of melting, and it is possible to enhance the strength by the inclusion of Μη, S i, and Cr. The effect of improving the oxidation resistance is fully exerted. Further, by including Mg, Al, and Ti', the workability of the nickel alloy (plastic workability such as rolling or drawing) can be improved, and the manufacturing property of the wire is excellent. If it is less than 0.001% by mass, it is difficult to sufficiently obtain the above effects, and if it exceeds 2.0% by mass, electrical conductivity or thermal conductivity is likely to be lowered. A more desirable total content is 0. 〇 〇 3 mass% or more and 1.5 mass% or less. The nickel alloy constituting the wire of the present invention and the strand of the present invention contains -13-201101366 containing the above-mentioned additive elements, and the residue is formed of Ni and unavoidable impurities. By setting the content of Ni to 90% by mass or more, as described above, it is excellent in oxidation resistance and it is difficult to form an oxide film. Therefore, it is easy to weld and is excellent in thermal conductivity. . [Mechanical characteristics] The wire of the present invention and the strand of the present invention have high strength as described above, and specifically, the tensile strength is 450 MPa or more. Further, the wire of the present invention and the strand of the present invention are excellent in toughness while being high in strength, and specifically, the elongation is 20% or more. Although depending on the composition or the wire drawing processing conditions, the heat treatment conditions, and the like, the wire of the present invention and the wire material of the present invention can be set to have a tensile strength of 500 MPa or more and an elongation of 40. More than % of wire. [Oxidation resistance] The wire of the present invention and the strand of the present invention are excellent in oxidation resistance as described above. Specifically, after the wire or the wire formed by the specific composition described above is heated in the air at 900 ° C for 72 hours, the thickness of the oxide film formed on the surface of the heated wire is The system is 100 # m or less. The condition of "900 ° C X 72 hours" is higher in temperature and higher by the heat condition given to the wire due to heat during welding or heat during melting of the glass. 14 - 201101366 The time system is longer, so it is a very strict condition. If the heating under such strict conditions is performed, the thickness of the oxide film is also thin enough to be evaluated as excellent in oxidation resistance. Therefore, in the present, as an index for evaluating the oxidation resistance, the condition of "heating at 900 ° C for 72 hours" is employed. When at least one of Si and Cr is contained as an additive element as described above, since it is more excellent in oxidation resistance, one form of the wire can be set to be in the atmosphere. After heating at ° C for 72 hours, the thickness of the oxide film was 60 /zm. Further, the wire to which the solder or the like is attached may be heated by the above conditions after the removal, and the oxidation may be determined. [Electrical Conductivity and Thermal Conductivity] The lead wire of the present invention or the strand of the present invention is excellent in electrical conductivity and thermal conductivity as described above. Although it is also dependent on the 'but the wire of the present invention or the wire material of the present invention, the resistance can be set to 0.2 " Qm or less, and the thermal conductivity is 45 W/m. K or more. [Manufacturing method] The wire or the present invention The wire material of the invention, for example, is solvable-casting-> heat-calendering-cold-drawn wire and heat-treated body, and the body can be made in a vacuum to make a nickel adjusted for the composition. In the invention, the general condition of the gas is generally determined by the line static tin removal film of 900, and the composition is such that the wire is melted by the electric wire. More alloy -15- 201101366 melt soup, and refining the melt, and the penalty for the content of C or the removal or reduction of impurities or inclusions, is to adjust the temperature. For this melt, the frequency of vacuum casting was carried out to obtain an ingot. Applying inter-heat rolling to this ingot to obtain the wire. The rolled wire is repeatedly subjected to cold drawing and heat treatment to the wire of the present invention or the strand of the present invention. The final system (softening treatment) can also be carried out, and in this case, it is preferably in the hydrogen atmosphere or in a nitrogen atmosphere, and is preferably about 700 to 1000 ° C, particularly 800 to 900 ° C left. Further, in the case where the strand of the present invention having a long strip shape is produced, it is suitably cut into a specific length, and the guide of the present invention is produced, which is excellent in productivity. [Wire member] The wire member of the present invention is provided with the above-described guide of the present invention and an inner conductor joined by welding at one end of the wire as in the above-mentioned general 'wire of the present invention, The surface tension is lowered during welding, and the wettability is excellent, so that it is strongly bonded to the inner wire. Therefore, the wire member of the present invention has a high welding strength. Examples of the inner conductor include a wire made of a Fe-Ni-Co alloy such as Kovar, a Dumei wire, and a wire made of Mo or the like.

And the wire member of the present invention, which is a wire of -16-201101366, and the glass portion to be joined; and the inner guide portion are joined. As described above, the wire of the present invention at the welded portion between the wire of the present invention and the above-mentioned inner wire is low in the amount of C, and the glass ball is fused at the inner wire to form a glass-containing gas. Therefore, the electrode member has substantially no gas glass tube at the glass portion, and examples thereof include a boric acid hard glass or a soda lime glass or the like, and may be exemplified by pure Ni, a nickel alloy described in _, Fe, Fe alloy, W, cup or column. [Cold Cathode Fluorescent Lamp] The cold cathode fluorescent lamp of the present invention is a glass tube of gas and is formed on the glass and the above electrode member. In the electrode portion of the glass tube electrode member, the electrode portion is fixed to the glass tube. The cold shade of the present invention is similar to the above-described conventional lead wire of the present invention having a high weld strength and high strength. Therefore, in the case of the lamp tube, even if the glass tube or the electrode portion of the glass tube is long, it is difficult to cause the electrode member to be bonded to the other end of the outer circumference of the inner lead wire. The wire length system of the present invention is high. Further, as described above, it is difficult to generate heat due to heating of the glass portion or the like, and the welding strength is high and foam. A glass part, and a soft glass such as a glass or an aluminum enamel glass described later. In the bottomed cylindrical shape formed by Mo or the like in the documents 1 and 2, the end portion of the phosphor layer which is filled with the inner wall of the sealed tube is inserted with the above-mentioned glass. The fluorescent lamp tube is preferably provided with the wettability between the solders, and the cold cathode fluorescent lamp of the present invention has a large diameter or a broken glass, or is fused to -17-201101366. The part or the solder part is detached, and it can be expected to be used for a long period of time. Moreover, by providing the wire of the present invention which is excellent in electrical conductivity or thermal conductivity, the cold cathode fluorescent lamp of the present invention is less likely to be accompanied by a wire even when a large current flows. From the point of view of this, it can be expected to be used for a long period of time. The phosphor layer may, for example, be a halogen phosphate phosphor. The gas to be enclosed is, for example, a rare gas and mercury, or mercury. At least one electrode portion is disposed in the glass tube, and the glass portion and the end portion of the glass tube are melted to be sealed. In a typical example, an electrode portion is disposed on both end sides of a cylindrical glass tube, that is, a shape in which a pair of electrode portions are provided. Hereinafter, embodiments of the present invention will be further described. A wire made of a nickel alloy was prepared as a wire to be used in a cold cathode fluorescent lamp, and the characteristics of each wire were evaluated. Sample Nos. 1 to 1 1 were produced as follows. Using a usual vacuum melting furnace, a molten alloy of a nickel alloy having a composition (unit: mass %) shown in Table 1 was prepared, and the temperature of the melt was appropriately adjusted, and an ingot was obtained by vacuum casting. Among the raw materials of the melted soup, pure Ni (99·0 mass% or more of Ni) and particles of each additive element which are commercially available are used. In order to reduce and remove impurities and the like, refining of the melt is carried out, and the content of C is changed by adjusting the degree of refining. -18-201101366 rolled wire having a wire diameter of 5.5 mm φ was obtained by applying inter-heat rolling to the obtained ingot. For this rolled wire, a cold drawn wire and a heat treatment were applied in combination, and a final heat treatment (softening treatment, temperature: 800 ° C, nitrogen atmosphere) was performed on the obtained wire to obtain a wire diameter of 0.6 mm φ. Soft material. Each of the soft materials was cut to an appropriate length, and samples No. 1 to 1 1 were used. The composition of each of the obtained samples was investigated by using an ICP emission spectroscopic analyzer. The results are the same as those shown in Table 1, and the residue is Ni and unavoidable impurities. Sample Nos. 1 to 11 were all 90% by mass or more of Ni. The analysis of the composition is carried out by the above-described ICp luminescence spectrometry, or by atomic absorption spectrometry or the like. Further, the amount of carbon of each of the obtained samples was measured by a high-frequency combustion infrared absorption method. The results are shown in Table 1. Sample No. 100 is a commercially available Mn-Ni alloy wire, and sample No. 102' is a commercially available Dumei wire (Cu coating: core material of the composition shown in Table 1 + C u When the coating is 1% by weight, it is 22.5 mass%). Further, in Sample No. 101, the additive element was less ’ and it was a refiner which was not used to reduce the content of C. The sample Νο·1〇3' has a large number of added elements, and is a sample prepared in the same manner as the above sample Nom. Sample No.1〇〇~103 is the wire diameter 〇 . 6mm φ. -19- 201101366

The result is: '2. The oxidation resistance was evaluated by the following method. Each sample was heated in the atmosphere for 9 hours: χ 72 hours, and it ' @ gt ® / photo was formed on the surface of the sample. The thickness of the oxide film was measured (sample No. 1 〇 2 for measuring the thickness of the oxide film formed on the surface of the Cu coating), and the thickness of the oxide film was evaluated. If the thickness of the oxide film is thinner, it can be said that the oxidation resistance is better. Here, in the cross-sectional photograph of each sample, the thickness of any five points was measured, and the average was taken as the thickness of the oxide film of the sample. The mechanical properties were evaluated for each of the above samples. The results of -20-201101366 are shown in Table 2. The mechanical properties were evaluated according to the specification of j! s z 2 2 4 1 and the tensile strength and elongation were measured. The strength (fatigue strength) of the welded portion was evaluated for each of the above samples. The results are shown in Table 2. The strength of the welded portion was evaluated by a rotational bending fatigue test (jis Z 2274) with a stress amplitude of 200 MPa and was repeated by the number of times. Specifically, in one of the end faces of each sample, a one end surface of a Kovar (Fe_Ni-Co alloy) wire sold in the market having a wire diameter of 0.6 mm φ was joined by resistance welding. Wire member. Then, the both end sides of the lead member (the other end side of the joined sample and the other end side of the Kovar wire) are clamped by the jig and the welded portion is placed at the place where the clamp is made. The mode at the center was used to perform a rotational bending test, and the number of times of overlap until the welded portion was broken was measured.电 The electrical conductivity and thermal conductivity were evaluated for each of the above samples. The results will not be shown in Table 2. The electrical conductivity was evaluated by measuring the specific resistance by a four-terminal method, and the thermal conductivity was measured by a commercially available laser flash device. The glass seal test was carried out for each of the above samples, and the state of foaming of the glass was investigated. The results are shown in Table 2. In this test, as in the above-mentioned general, a wire member in which each sample is melted with a commercially available Kovar wire is prepared, and the wire members are oxidized, and a plurality of oxide films are formed on the surface thereof, and then The glass beads were fused by melting the glass on the section of the Kovar line-21 - 201101366, the welded portion, and one of the samples, and then the foamed state of the glass was observed by visual observation. . When there was foaming in the glass, it was evaluated as X, and when there was no foaming, it was evaluated as 〇.

Further, it can be seen that at least one of the contents of Μη, Si, Cr, and the content of C is a sample No. 100, 101, and 1 落3 which falls outside the specific range, and the sample N 〇 1 ~1 1 ' has a good balance and strength and toughness. Sample N〇. i~ -22- 201101366 11 'Because it is not only a soft material to which the final softening treatment is applied, but also high strength, even when there is heat due to welding or glass melting In the case of a heat history caused by heat or the like, it is expected that it can maintain a sufficiently high strength. Further, Sample Nos. 1 to 11 showed that the fatigue strength of the welded portion was higher than that of Sample No. 100 and 101 or Sample No. 1 02 which was Dumet wire. Further, Sample No. 1 to 1 1 was also excellent in oxidation resistance. Even if it was heated in the atmosphere at 900 ° C for 7 hours, the thickness of the oxide film was also l〇〇. /zm or less (more than 60/im or less). Samples Nos. 1 to 11 which are excellent in oxidation resistance are expected to have high wettability with solder.

Further, it can be seen that the sample Nos. 1 to 11 in which the amount of C is contained is small, and even when the glass is melted, it is difficult to generate bubbles inside the glass. On the other hand, it can be seen that in Sample Nos. 100 and 101 in which the content of C is large, bubbles are generated inside the glass. Therefore, it is conceivable that if the content of C is large, it is easy to generate a gas containing carbon, and it is easy to generate bubbles. As described above, one or more of Mn, Si, and Cr are in a specific range. It is excellent in electric conductivity and thermal conductivity, and it is excellent in electric conductivity and thermal conductivity, not only in the strength of the local strength, but also in the strength of the welded portion and the wettability between the solders. -23-201101366 It is expected that it is suitable for use in a wire such as a cold cathode fluorescent lamp, a wire member having the wire, and a cold cathode fluorescent lamp having an electrode member having the wire member.

In particular, the wire made of the above-mentioned specific wire material is a component of a cold cathode fluorescent lamp having a length of 1 300 mm or more for a glass tube, or a diameter of 4.0 mm for a glass tube or the like. It is also expected that the components of the large-caliber cold-cathode fluorescent tube having a diameter of φ or more can be sufficiently used. Further, the cold cathode fluorescent lamp having the wire formed of the above-mentioned specific wire material is less likely to cause breakage of the wire or breakage of the welded portion, and the inside of the glass tube due to the presence of the bubble Gas leakage or problems caused by heat can be expected to have a long service life.
