Abstract: The present disclosure relates to a wearable device having a structure that prevents impedance measurement errors. The wearable device, which is used by being attached to the skin of a user, includes a plurality of electrodes spaced apart from each other, conductive members, blocking members, and absorbent members. A conductive member is positioned on one surface of each of the plurality of electrodes and comprises an exposure portion. A blocking member includes a different material from the conductive member and covers an outside of the conductive member so that the exposure portion is present within the blocking member. An absorbent member is positioned in the outside of the blocking member and comes into contact with the skin of the user.
