To provide an electronic apparatus having a software keyboard reducing erroneous operation during character input.

Upper-stage and lower-stage key arrays are constituted such that a long side opposed to a mountain part MP of a character key 311 forms a base BL, and bases are arrayed on a straight line. Each of the upper-stage and lower-stage key arrays, in which two oblique sides SL forming the mountain part MP form valleys with oblique sides of adjacent character keys 311, has a contour such that mountains and valleys are complementarily arranged. The upper-stage and lower-stage key arrays are arranged so that sides having contours where mountains and valleys are complementarily arranged face each other, and upper and lower character keys 311 are arrayed zigzag, and the mountains and valleys of the upper-stage and lower-stage key arrays mesh with each other across a gap.
