If the distance D2 between the first side surface S1 of 41 and the first light-emitting element 21 is smaller than the range, the first side Light loss through surface S1 increases. The spacing K1 between the side S11s is 3.5 mm or less, for example, in the range of 2.5 mm to 3.5 mm. However, if it is smaller than the aforementioned range, the heat dissipation efficiency will decrease or the wavelength conversion efficiency of the first light will increase. It can be added.

[0022] The second resin part 43 may be provided without a phosphor. That is, the second resin part 4 3 is provided with a small width W2, so when a phosphor is added inside, the wavelength of the second light changes.

The thickness T1 of the first and second resin parts 41 and 43 is 4 mm or less, for example, 1.8 mm. It can have a range of m to 4 mm or a range of 1.8 mm to 3.5 mm. Since the thickness T1 of the second resin parts 41 and 43 is provided within the above range, a flexible module is provided. It is supplied in a syrup and can improve light extraction efficiency and light distribution. The first resin part 4 The upper surface area of ​​1 may be larger than the upper surface area of ​​the second resin part 43. The upper surface area of ​​1 may be twice or more the upper surface area of ​​the second resin part 43. The upper surface of the grease portion 41 is provided as a surface from which light is emitted. The width of the lower surface of the first resin portion 41 is The width of the top surface (for example, W1) may be the same. The top surface of the first resin part 41 is flat.

The side surface S2 of the second reflective portion 61B can face the first side surface S1. The reflective layer 61 can overlap the phosphor portion 45 in a perpendicular direction. The reflective layer 61 is The reflective layer 61 can contact the upper surface of the second resin part 43. It can contact the upper surface of 43 and the upper end of the phosphor portion 45. When the upper end comes into contact with the diffusion layer 51, light that has not been wavelength-converted leaks through the diffusion layer 51. Leakage may occur. As a result, the upper end of the phosphor portion 45 is exposed to the reflective layer 61 It is positioned in contact with the lower surface. The reflective layer 61 can come into contact with the diffusion layer 51. The interface between the reflective layer 61 and the diffusion layer 51 extends from one surface of the phosphor portion 45. One surface of the phosphor portion 45 may be the surface that is in contact with the inner surface of the first resin portion 41.
