The sinter-bonding composition contains sinterable particles containing an electroconductive metal. The average particle diameter of the sinterable particles is 2 &#x3bc;m or less and the proportion of the particles having a particle diameter of 100 nm or less in the sinterable particles is not less than 80% by mass. The sinter-bonding sheet () has an adhesive layer made from such a sinter-bonding composition. The dicing tape with a sinter-bonding sheet (X) has such a sinter-bonding sheet () and a dicing tape (). The dicing tape () has a lamination structure containing a base material () and an adhesive layer (), and the sinter-bonding sheet () is positioned on the adhesive layer () of the dicing tape ().

A method of producing a polarizing film having a high polarizing function. Provided is a method of producing a polarizing film, including the steps of: at least dyeing and stretching a first polyvinyl alcohol of two or more band-like polyvinyl alcohol films in the course of a traveling path while traveling the first polyvinyl alcohol film in a longitudinal direction, and bonding a tail end of the first polyvinyl alcohol resin film to a leading end of a second polyvinyl alcohol resin film to at least dye and stretch the first and second polyvinyl alcohol resin films continuously, wherein the first and second polyvinyl alcohol resin films are arranged with the tail end of the first polyvinyl alcohol resin film and the leading end of the second polyvinyl alcohol resin film being layered, and an interface portion thereof is laser welded to perform the bonding.
