`
`The present invention realizes calculating a pulse rate accu(cid:173)
`rately, even wben a body movement component has no
`periodical characteristics, by surely removing the body
`movement component generated in a living organism from
`a pulse wave component. A pulse wave detecting section
`includes a pulse wave sensor and outputs a pulse wave
`detection signal to au MPU functioning as a body motion
`component removing section. A body motion sensor outputs
`a body motion detection signal corresponding to a body
`motion that affects the behavior of venous blood to the
`MPU. As a result, to tbe Ml'U removes the body motion
`component from tbe pulse wave detection signal based on
`the body motion detection signal. A pulse rate calculating
`section calculate-s the pulse rate based on tbe pulse wave
`detection signal from which the body motion component bas
`been removed. The pulse rate is displayed on a liquid crystal
`display device.
