Disclosed is a brushless motor (A) which is an axial gap type brushless motor (A) wherein stators (A,A) comprising a coil () and a rotor () comprising a permanent magnet () are arranged with a gap therebetween in the axial direction. The coil () is a band-like wire which is spirally wound such that the width direction of the band-like wire generally coincides with the direction of the magnetic flux that is generated by the permanent magnet () of the rotor (). Consequently, the axial gap type brushless motor (A) having the above-described structure can be further reduced in eddy current loss in comparison to conventional brushless motors.

A method for manufacturing a porous dielectric substrate including patterned electrodes includes a patterned electrode-forming step of preparing a support plate having a releasable flat face and then forming the patterned electrodes on the flat face, a porous dielectric substrate-forming step of feeding a material for forming the porous dielectric substrate onto the flat face having the patterned electrodes arranged thereon to form the porous dielectric substrate in which the patterned electrodes are embedded, and a separation step of separating the support plate from the porous dielectric substrate having the patterned electrodes embedded therein. In the patterned electrode-forming step, the patterned electrodes formed on the flat face are processed to have rough surfaces in the patterned electrode-forming step. Alternatively, after the flat face is coated with a releasing agent, the patterned electrodes are formed on the resulting flat face.

A dielectric line having a sufficient ensured strength and being suitable for mass production and a production method therefor are provided. The production method is a method for manufacturing a dielectric line having a dielectric strip which is provided between two conductive plates approximately parallel to each other and which has a width smaller than that of the conductive plates, and dielectric medium layers which are filled between the conductive plates other than the dielectric strip and which is composed of a porous material having a dielectric constant smaller than that of the dielectric strip. The dielectric line (NRD guide) is produced by film forming steps Sand Sin which a film of a dielectric raw material is formed on one of the conductive plates, a strip exposure step Sin which a part of the above film having a shape corresponding to the dielectric strip is exposed to predetermined light, beams, or vapor, and pore forming steps Sand Sin which the entire film of the dielectric raw material is made porous.

A feed antenna includes a pair of conductive members, a dielectric waveguide placed therebetween, a dielectric member that is placed between the conductive members and located close to the dielectric waveguide, and a plurality of dielectric binding sections for binding the dielectric waveguide to the dielectric member. One of the conductive members has a plurality of openings.
