Electronic circuit device

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.
