Abstract:
1. A base of an electronic component package for holding an electronic component element, wherein the base has a bottom surface having a rectangular shape as viewed from above, and on the bottom surface, a plurality of terminal electrodes that are to be joined to an external circuit substrate using a conductive adhesive material are formed; a first terminal electrode group including two or more of the terminal electrodes formed in parallel is formed eccentrically to one corner position of the bottom surface; a second terminal electrode including one of the terminal electrodes or a second terminal electrode group including two or more of the terminal electrodes formed in parallel is formed eccentrically to a first diagonal position diagonally opposite the one corner position of the bottom surface; another corner position facing the one corner position in a short side direction of the bottom surface, and a second diagonal position diagonally opposite the other corner position of the bottom surface, are no-electrode regions in which none of the terminal electrodes is formed; and at least one of the plurality of terminal electrodes is a ground terminal electrode.
