Abstract: A fluidized-bed coating method includes: immersing at least part of a workpiece in a powder coating material contained in a fluidized-bed vessel while air is introduced from a bottom of the fluidized-bed vessel at an average air flow rate of 5 mm/min or higher and 20 mm/min or lower per unit area of the bottom so that a floating ratio of the powder coating material is 5% or higher and 20% or lower, the workpiece having a temperature higher than or equal to a softening temperature of the powder coating material and lower than or equal to a melting temperature of the powder coating material; taking the workpiece out of the powder coating material; and heating the powder coating material attached to the workpiece.

Abstract: A porous polyimide film has a ratio of a cross-sectional average micro pore diameter (μm) to a first surface micro pore diameter (μm) on one surface (the cross-sectional average micro pore diameter/the first surface micro pore diameter) of equal to or more than 5 and equal to or less than 10.
