Abstract: The present invention provides a core block for a motor and a method for producing the core block, which can be efficiently produced and in which the size of a plastic region with poor properties that is formed on an electromagnetic steel sheet of the core block is reduced. This core block for a motor comprises electromagnetic steel sheets laminated on each other, said core block being obtained by carrying out an edge part forming process using electrical energy or optical energy to form the whole or part of the circumferences of edge parts of the electromagnetic steel sheets of the core block and carrying out press working to punch the electromagnetic steel sheets before or after the edge part forming process that uses electrical energy or optical energy.

Abstract: Provided is a decorative sheet (100) including: a transmissive substrate (10) which is sheet-like or plate-like; a light reflective projection portion (20) formed over the light transmissive substrate (10); and a black layer (30) formed over the light reflective projection portion (20), in which an average height of the light reflective projection portions (20) is 1 to 200 pm, and the black layer (30) is formed by using a black ink satisfying conditions below.
