The purpose of the present invention is to provide an antenna receiving device, an antenna holder, and a receiving device, with which each receiving antenna can be easily adjusted to a prescribed receiving location upon an antenna holder irrespective of a subject's physique. Provided is an antenna receiving device, comprising: a belt-shaped sheet unit (51) to which a plurality of receiving antennae (4) are detachably connected, said receiving antennae (4) receiving information which is transmitted from a device which is introduced within a subject, and said belt-shaped sheet unit (51) being wound about and mounted upon the torso of the subject; shape detection units (52) which are disposed upon the outer surface of the sheet unit (51) in the longitudinal direction of the sheet unit (51), and which detect the shape of the sheet unit (51); an inference unit (651) which, on the basis of the shape of the sheet unit (51) which the shape detection units (52) have detected, infers the cross-section shape of the torso of the subject; a location definition unit (652) which, on the basis of the cross-section shape which the inference unit (651) has inferred, defines a plurality of indicators (M1) which correspond to the respective attachment locations of the plurality of receiving antennae (4) upon the sheet unit (51); and a display unit (63) which displays indicator information which denotes the plurality of indicators (M1) which the location definition unit (652) has defined.La présente invention vise à fournir un dispositif de réception d'antenne, un support d'antenne et un dispositif de réception, avec lesquels chaque antenne de réception peut être ajustée facilement à un emplacement de réception prescrit sur un support d'antenne, indépendamment du physique d'un sujet. L'invention concerne un dispositif de réception d'antenne qui comporte : une unité de feuille en forme de bande (51) à laquelle une pluralité d'antennes de réception (4) sont reliées de façon détachable, le
