The scanning antenna (1000) is a scanning antenna in which antenna units (U) are arranged, the scanning antenna comprising: 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), and a slot electrode (55); a liquid crystal layer (LC) provided between the TFT substrate and the slot substrate; a sealing portion that envelopes the liquid crystal layer; and a reflective conductive plate (65). The slot electrode includes slots (57) arranged in correspondence with the plurality of patch electrodes. The sealing portion includes a main sealing portion (73Fa) that defines an injection port (74Fa) and an end sealing portion (75Fa) that seals the injection port (74Fa). The end sealing portion (75Fa) is formed of a thermosetting sealant material. |
