Claim 18:
19. A method for manufacturing a terahertz device comprising a terahertz element configured to perform conversion between terahertz waves and electric energy and having an element front surface and an element back surface spaced apart from each other in a first direction, the method comprising:
a support board preparation step for preparing a support board having a support-board front surface and a support-board back surface facing away from each other in the first direction;
a frame-shaped member forming step for forming a frame-shaped member from a conductive material on the support board;
a wiring layer forming step for forming a wiring layer electrically connected to the terahertz element;
an element mounting step for mounting the terahertz element on the support board such that the frame-shaped member is positioned around the terahertz element as viewed in the first direction;
a sealing resin forming step for forming a sealing resin covering the terahertz element; and
a grinding step for grinding the support board,
wherein the frame-shaped member has a reflective surface capable of reflecting the terahertz waves.
