1. An acoustic-wave measuring device comprising:
a support table having a support surface configured to support an examination subject, and an opening portion in the support surface to measure a predetermined examination site of the examination subject;
a container vertically below the support surface and configured to contain a first acoustic matching material in liquid or gel form;
a placement unit between the first acoustic matching material contained in the container and the examination site;
a matching-material bag containing a second acoustic matching material in liquid or gel form, the matching-material bag being on the placement unit between the first acoustic matching material in the container and the examination site; and
a receiving element vertically below the support surface and configured to receive an acoustic wave generated from the examination site via the first acoustic matching material, the placement unit, and the matching-material bag, wherein
the matching-material bag has a bag body film surrounding a storage space containing the second acoustic matching material, and
the bag body film is configured to prevent the examination subject from directly contacting the second acoustic matching material.
