PROBLEM TO BE SOLVED: To provide an ear wearing tool with pulse sensor which enhances design freedom.SOLUTION: An ear wearing tool with pulse sensor 1 includes: a housing 3; a pulse sensor 5; and a light guide member 6. The housing includes an insertion part 11 capable of being inserted into an ear hole when the ear wearing tool is worn on a user's ear, the insertion part including an exposure hole 12 facing an inner wall of the ear hole. The pulse sensor is attached to the housing, irradiates the inner wall of the ear hole with light with a light emitting element 21 and receives light returning from the inner wall of the ear hole with a light reception element, thereby capable of measuring the user's pulse. The light guide member is long shaped and attached on the housing in a state in which one end 25 in a longitudinal direction is inserted into the exposure hole of the insertion part and the other end 26 in the longitudinal direction faces the pulse sensor so as to transmit light from the inner wall of the ear hole to the light reception element.SELECTED DRAWING: Figure 2 |
