A scanned antenna (1000) is a scanned antenna including antenna elements (U) arranged together, the scanned antenna including: a TFT substrate (101) including a first dielectric substrate (1), TFTs, gate bus lines, source bus lines, and patch electrodes (15); a slot substrate (201) including a second dielectric substrate (51) a slot electrode (55); a liquid crystal layer (LC) provided between the TFT substrate and the slot substrate; and a reflective conductive plate (65). The slot electrode includes slots (57) arranged so as to correspond to the patch electrodes. As seen from the normal direction to the first dielectric substrate, a plurality of spacer structures (75) provided between the TFT substrate and the slot substrate are arranged so as not to overlap with first regions (Rp1) and/or second regions (Rp2), where the first regions are regions that are within a distance of 0.3 mm from edges of the slots and the second regions are regions that are within a distance of 0.3 mm from edges of the patch electrodes.
