An element-accommodating package (1) is provided with: a rectangular substrate (2) having on the top surface a region (R) for mounting an element; a frame (3) provided along the outer periphery of the mounting region (R) on the substrate (2), the frame (3) having a notch (C) in one section; and an input-output terminal (4) provided in the notch (C) and extending from a region surrounded by the frame (3) to a region not surrounded by the frame (3). The input-output terminal (4) includes a first insulating layer (4a), a second insulating layer (4b) laminated on the first insulating layer (4a), and a third insulating layer (4c) laminated on the second insulating layer (4b). A plurality of first terminals (6) set to a predetermined potential are provided to the top surface of the first insulating layer (4a), a plurality of second terminals (7) set to a predetermined potential are provided to the bottom surface of the first insulating layer (4a), and a plurality of third terminals (8) through which an alternating-current signal is passed are provided to the top surface of the second insulating layer (4b). |
