1. An electronic circuit device comprising:

  • a printed wiring board having a major surface and pads provided on the major surfaces;

    a leadless component located above the major surface of said printing wiring board and having a major surface opposing the major surface of said printed wiring board;

    a plurality of electrodes which are each provided on at least a part of the major surface of said leadless component and one side of said leadless component;

    a plurality of bumps electrically connecting said pads to said plurality of electrodes, respectively, so as to provide a distance between opposing ones of said plurality of electrodes of said pads;

    a plurality of electrically conductive members integral with said bumps, each one of said plurality of electrically conductive members extending from one of said bumps onto a region of one of said plurality of electrodes that is provided on a side of said leadless component; and

    a spacer located in a gap between the major surface of said leadless component and the major surface of said printed wiring board,wherein the outermost part of each one of said plurality of bumps is located above outside an outer edge of a corresponding one of said pads, as said leadless component is viewed from above.
