Abstract: A radio wave reflection reducing sheet provided with a laminate having a first primary surface and a second primary surface is disclosed. The laminate has: a first resin foam layer having a thickness from 0.05 to 3.00 mm and a density from 0.10 to 0.85 g/cm3, and a second resin foam layer having a thickness from 0.05 to 3.00 mm and a density from 0.20 to 0.90 g/cm3. The density of the second resin foam layer is greater than the density of the first resin foam layer. The first resin foam layer and the second resin foam layer are disposed in this order from the first primary surface side.

Abstract: A stator includes: a plurality of divided cores disposed to have a ring shape; a stator winding toroidally wound on the stator; and a holding member that holds the divided cores in the ring shape. Each of the divided cores includes: a bobbin part for the stator winding; a yoke extending from the bobbin part in the circumferential direction; a connection part extending from the yoke outwardly in a radial direction with a connection face that is connected to the holding member; and a tooth extending from the yoke inwardly. The connection part has a magnetic gap to increase a magnetic resistance in a path of magnetic flux, generated by the stator winding, leaked to the holding member through the connection face. The magnetic gap is a notch or a weld.
