Disclosed is a separator in which a porous coating layer is formed of a mixture of inorganic material particles and a binder polymer on the surface of a porous substrate.

A primary objective of the present invention is to provide a solid cell with which it is possible to alleviate short-circuits between electrodes. The present invention is a solid cell, comprising a first electrode layer, a second electrode layer, and a solid electrolyte layer which is positioned between the first electrode layer and the second electrode layer. A first insulation layer is positioned upon the exterior circumference of the first electrode layer. The size of the stack face of the first electrode layer, taking the stack direction of the first electrode layer, the solid electrolyte layer, and the second electrode layer as the direction of the normal thereof, is smaller than the size of the stack face of the solid electrolyte layer. When viewed from the stack direction, the outer edge of the solid electrolyte layer is located upon the exterior circumference of the first electrode layer, and the outer edge of the first insulation layer is located on the exterior circumference of the solid electrolyte layer. The first electrode layer, the first insulation layer, and the solid electrolyte layer are positioned such that the outer edge of the first insulation layer and the end parts of the solid electrolyte layer make contact.

The invention provides a waterproof connector and a manufacturing method thereof. A waterproof connector (10) has: at least one conductive contact (12); a metal shell (16) interior of which the contact is disposed; and a housing (32) made of an insulating resin material such that the housing fixes the contact and the shell to form an integral structure, the shell has an insertion port (21) into which a counterpart connector is inserted on one side, and the housing is formed such that the shell is exposed at the outer circumference of and at the vicinity of the insertion port over a predetermined width in the length direction of the shell to form an outer circumferential exposure portion (24), and the outer circumferential exposure portion of the shell is disposed with a waterproof portion (49) made of an elastic material.

A charge-transporting thin film having excellent flatness can be obtained with good repeatability using the charge-transporting varnish of the present invention, which contains: a charge transportation substance comprising a charge-transporting monomer or a charge-transporting oligomer or polymer having a number-average molecular weight of 200-50,000, or a charge transporting material comprising the charge transportation substance and a dopant substance; and a mixed solvent including at least one type of good solvent and at least one type of poor solvent; the absolute value of the boiling point difference DeltaT°C of the good solvent and the poor solvent satisfying the relation |DeltaT| < 20°C; the viscosity at 25°C being 7.5 mPa.s or less; the surface tension at 23°C being 30.0-40.0 mN / m; and the charge-transporting material being dissolved or uniformly dispersed in the mixed solvent.
