To provide a bathtub apparatus capable of detecting a cardiac signal with sufficient amplitude even when applied to a bathtub with a wide backrest surface.SOLUTION: A bathtub apparatus (1) having a cardiac signal detection function comprises: a bathtub body (2) formed in an approximately rectangular shape in a plan view; and a pair of electrodes composed of a positive electrode (4b) and a negative electrode (4a) attached to the bathtub body to detect a bather's cardiac signal via warm water retained in the bathtub body. The pair of electrodes are both arranged on a first inner wall surface (2a) which constitutes a narrow side of the bathtub body, and the positive electrode and the negative electrodes are disposed on the left and right sides respectively of a center line (C) that passes through the center in the horizontal direction of the first inner wall surface.SELECTED DRAWING: Figure 1 【課題】背もたれ面の幅の広い浴槽に適用した場合でも、十分な振幅で心電信号を検出することができる浴槽装置を提供する。【解決手段】本発明は、心電信号の検出機能を備えた浴槽装置(1)であって、平面視において、略長方形に形成された浴槽本体(2)と、この浴槽本体内に貯留された湯水を介して入浴者の心電信号を検出するための、浴槽本体に取り付けられた正電極(4b)、及び負電極(4a)からなる一組の電極と、を有し、一組の電極は、何れも浴槽本体の短辺を構成する第１の内壁面(2a)上に配置され、正電極及び負電極は、第１の内壁面の水平方向の中心を通る中心線(C)の左右に夫々配置されていることを特徴としている。【選択図】図１
