This allows body hair to be discharged from the opening windows 210 still more smoothly.
  • the inner blade attachment portions 131 and 141 are configured not to vertically overlap the opening windows 210 in the front view of the electric razor 1. Accordingly, water introduced from the opening windows 210 collide with the inner blade attachment portions 131 and 141 and cannot reach deep inside (the back side). It is, therefore, possible to improve the performance of cleaning the space portion S.
  • the head case cover 81 as the bottom face defining the space portion S includes the slope portions 81c that slope from the center in the front view of the electric razor 1 toward the opening windows 210. This allows water in the central part of the head cover 81 to flow easily to the opening windows 210 along the slope portions 81c. Accordingly, the inside of the space portion S can be cleaned more efficiently.
  • the upper face of the head case cover 81 slopes forward and downward when the electric razor 1 is stood up (as illustrated in Fig. 4 : in such a state where the grip portion 2 is stood substantially vertically). In other words, the upper face of the head case cover 81 slopes such that the side provided with the opening windows 210 is lower. Accordingly, this embodiment also has such an advantage that the space portion S can be dried more efficiently when the electric razor 1 is stood up.
  • the plural opening windows 210 can be opened and closed by one operator 203.
  • the plural opening windows 210 can be opened and closed with one operation, thus facilitating opening and closing the opening windows 210.
  • the operator 203 is provided for one of the plural opening windows 210, the operator can be located more flexibly, thus improving in design.
  • the inner blades may be reciprocated using a rotary motor and a conversion mechanism in the embodiment.
  • an electric razor in which the operator opening and closing the opening can be prevented from being accidentally operated when the electric razor is in use.
