Provided is a capsule medical system and the like which can stably and precisely detect the position of the capsule medical device while suppressing the power consumption of the battery contained in the capsule medical device. The capsule endoscope 10 includes a power supply unit 140 including a battery, a magnetic field generation unit 150 that generates a magnetic field by receiving supply of electric power from the power supply unit 140, and power supply from the power supply unit 140 to the magnetic field generation unit 150 A control unit 120 for controlling the imaging unit 110 and an imaging unit 110 for receiving information on the inside of the subject by receiving power supply from the power supply unit 140. The control unit 120 synchronizes with the operation of the imaging unit 110 and controls the power supply unit 140 To intermittently supply electric power to the magnetic field generation unit 150.カプセル型医療装置が内蔵する電池の消費電力を抑制しつつ、カプセル型医療装置の位置を安定的に精度良く検出することができるカプセル型医療システム等を提供する。カプセル型内視鏡10は、電池を含む電源部140と、該電源部140から電力の供給を受けて磁界を発生する磁界発生部150と、電源部140から磁界発生部150への電力供給を制御する制御部120と、電源部140から電力の供給を受けて被検体内に関する情報を取得する撮像ユニット110とを備え、制御部120は、撮像ユニット110の動作と同期して、電源部140から磁界発生部150に間欠的に電力供給がなされるように制御を行う。
