Zusammenfassung:PROBLEM TO BE SOLVED: To provide a pulse wave sensor capable of reducing a noise light and having high detection probability. SOLUTION: This reflection type pulse wave sensor having a light emitting element 3 and a light receiving element 4 is disposed with a light control film 10 on the upper part of the light receiving element 4. This constitution can cut off disturbance light whose incident angle is a prescribed value (for example 35°) or more so as to reduce false detection due to the effect of the disturbance light and improve the detection probability.
