Abstract
A method for connection of a flexible circuit board to a rigid circuit board is provided. The method includes supplying an adhesive agent onto a first electrode pattern provided on one surface of the rigid circuit board. The rigid circuit board has a plurality of electronic components mounted on the other surface with a gap therebetween. The method also includes aligning a second electrode pattern provided on the flexible circuit board to the first electrode pattern of the rigid circuit board. The adhesive agent is heated under pressure to electrically connect the second electrode pattern to the first electrode pattern by pressing the gap between the plurality of electronic components with a jig which has a press-contact section of a narrower width than the gap.
