PROBLEM TO BE SOLVED: To provide an inner blade unit having a configuration contributing to the improvement of assemblability, and an electric shaver having the inner blade unit.SOLUTION: An inner blade unit has an inner blade and an inner blade joint part. The inner blade joint part has a joint body part and a joint vibration part 70. The joint vibration part 70 has a vibration part body part 71 and a connection part 100 for a blade piece. The connection part 100 for a blade piece is formed integrally with the vibration part body part 71, and has a first blade piece facing surface 111 and a second blade piece facing surface 121. The first blade piece facing surface 111 has a first facing surface contact part 112 and a first facing surface separation part 113. The second blade piece facing surface 121 has a second facing surface contact part 122 and a second facing surface separation part 123. The first facing surface separation part 113 is formed side by side with the first facing surface contact part 112 in an inner blade depth direction DX. The second facing surface separation part 123 is formed side by side with the second facing surface contact part 122 in the inner blade depth direction DX. |
