The present invention provides a capsule type medical apparatus that can receive, in a subject, an external signal transmitted from an outside of the subject and transmitted via a conductor existing in the subject, including: a cover member that is formed of a dielectric and covers components of the capsule type medical apparatus a plurality of electrodes that are formed of conductors, are provided in tight contact with an inner wall side surface of the cover member, and receive the external signal an inductor circuit that is connected in series to each of the plurality of electrodes, and has an inductance value set to configure a resonant circuit having a frequency substantially equal to a carrier frequency of the external signal as a resonant frequency and a signal receiving circuit to which the external signal received by the plurality of electrodes and a potential difference of the external signal are inputted.
