Claim 19:
20. An acceleration detection device comprising:
a board including a first surface and a second surface facing away from the first surface;
an acceleration detector mounted on the first surface of the board;
a first circuit component mounted on the second surface of the board;
a seal including a first sealing portion covering the acceleration detector on the first surface of the board and a second sealing portion covering the first circuit component on the second surface of the board, the second sealing portion including an inner surface facing the board and an outer surface on a side opposite to the inner surface, the seal being made of a resin; and
a high-rigidity body extending in a direction in which the outer surface and the second surface of the board are connected to each other within the second sealing portion; wherein
the high-rigidity body has higher rigidity than the seal; and
a plurality of high-rigidity bodies are provided in a region in which the acceleration detector overlaps the board as seen in a direction in which the outer surface and the second surface of the board are connected to each other, the high-rigidity body being one of the plurality of high-rigidity bodies.
