Abstract

The present invention provides conductive particles which are less susceptible to agglomeration, and which improve conduction reliability of an obtained connection structure even in cases where conductive connection is performed at relatively low temperatures. Conductive particles (1) according to the present invention each have a base material particle (2) and a conductive part (3) that is disposed on the surface of the base material particle (2). The conductive part (3) contains tin and indium. When an X-ray diffraction spectrum of the conductive part (3) is measured, a peak exists in the range of 20.5° to 23.5° and in the range of 32.5° to 34°, and the ratio P of the area of the peak that is present in the range of 20.5° to 23.5° to the area of the peak that is present in the range of 32.5° to 34° is 0.0001 to 0.2 inclusive.

Abstract

The interlayer film for laminated glass (1) according to the present invention comprises a functional film (10) and one or more first polymer sheets (20a, 20b) provided on one surface (11) of the functional film (10). In a projected view in the thickness direction, the functional film (10) is included at least in a region of the first polymer sheet (20a) among the one or more first polymer sheets (20a, 20b) that contacts the functional film. One or more gap filler polymer sheets (30) are further comprised provided to the opposite side from the functional film side of the first polymer sheet(s) (20a, 20b). The laminated glass according to the present invention comprises a pair of glass plates, and the interlayer film for laminated glass 1 provided between the pair of glass plates. According to the present invention, it is possible to provide an interlayer film for laminated glass that can reduce the size of a gap occurring at an end of a functional film while also preventing the occurrence of a level difference in the thickness direction, laminated glass, and a production method for an interlayer film for laminated glass.
