An object of the present invention is to easily start to operate a body-insertable apparatus which is introduced into a subject and executes a predetermined function. In a capsule endoscope 3 of the invention, a magnetic switch 14 is arranged in a tubular capsule casing 16 of the capsule endoscope 3 in a direction substantially perpendicular to a longitudinal axis t direction of the capsule casing 16 . A movable electrode of the magnetic switch 14 is brought into contact with a fixed electrode of the magnetic switch by a magnetic induction action by a magnetic field generated by a magnet 6 , which is applied to the magnetic switch 14 from the outside of the capsule endoscope 3 in a direction substantially parallel to the longitudinal axis t direction of the capsule casing 16 . As a result, electric power can be supplied from a power source unit to a function executing unit. |
