(canceled)

A detection method including:

• changing a volume of a volume change body depending on an amount of a target, the volume change body being supported by a body member so that at least a part of the volume change body is stored in a storage space, the body member having a flat plate-like shape, a first end in a first direction being supported, and the storage space opening at at least one of end faces in a thickness direction;
• and
• detecting stress caused by the change in the volume of the volume change body in a detection member that is in contact with a second end in the first direction of the body member.

A sensor manufacturing method including:

• forming a storage space in a first member, the first member having a flat plate-like shape and a first end in a first direction being supported, the storage space opening at at least one of end faces in a thickness direction, and providing an element in a second member in contact with a second end in the first direction of the first member, the element detecting stress;
• and
• storing at least a part of the volume change body, whose volume changes depending on an amount of a target, in the storage space so as to be supported by the first member.
