Abstract
A printed circuit board has a terminal area to which the terminal area of a sheet member is electrically connected. The sheet member is bonded to the printed circuit board with a hot-melt adhesive. The layer of the hot-melt adhesive which is formed on the sheet member and does not face the terminal area of the printed circuit board protrudes from the surface of the terminal area of the sheet member. The printed circuit board includes an insulating substrate made from a material containing silicon dioxide. A metal salt that imparts hydrophobicity to the bonded surface of the substrate is added to the layer of the hot-melt adhesive.
