A barrier film for a wavelength conversion sheet, which can effectively suppress adhering of a light guide plate to the wavelength conversion sheet and suppresses damaging of a wavelength conversion sheet, a light guide plate, a diffusion plate, etc. A barrier film includes at least a barrier layer and base material layers. The barrier film has stacked on one surface thereof a mat layer including a resin and fillers which at least partially project from the mat layer. In a plan view, the proportion of the projecting fillers from the mat layer that are viewed as having a particle size at least twice the thickness of the mat layer is 20-80% of the total fillers projecting from the mat layer, and the total number of fillers in a square of 1 mmin the plan view of the mat layer is 1800 or more.

A holding jig is made into cylindrical body that has a conductor insertion aperture, and a conductor end portion is inserted into the conductor insertion aperture in a loosely-fitted state and held. The holding jig is moved along an arc that has a radius L that is centered around a projecting root portion of the conductor end portion to a vicinity of a coil end to bend and form the conductor end portion into a desired lead around shape.
