Body
The body is stainless steel. Early sets used corrugated panels, while sets made after 1987 had a beaten style. (Some corrugated-style cars were made after 1987 as middle cars for sets made early in production.) The sides were not painted. Fronts of early sets were the same color as the sides. The front designs are of two types, but the difference is minor.

The driver's cab contains a T-shaped, one-handle master-controller system. The speedometer is analog, providing information up to 140 km/h (87 mph).

Used on all Keio Corporation lines. (excluding Inokashira Line)
- For daytime operation, 10-car sets or 10-car trains of six-car sets coupled to four-car sets are used as Special Express and Semi Special Express trains.
- Eight-car trains of six-car sets coupled to two-car sets are used mainly as Local or Rapid trains.
The 7000 series began service in 1984. The 7000 series was built for local train service, and the first sets were five-car sets, rather than 4, 6 or 10 cars. The running performance of the new series was nearly the same as the Keio 6000 series.[10] By 1996, 190 cars of the 7000 series had been built.
From 2001, 7000 series sets were introduced on Special Express, Semi Special Express, Express, and Rapid trains.[11]
Keio announced in 2010 that 18 more of its 7000 series cars would be converted to VVVF inverter control.[12] By 2012, the entire fleet was retrofitted with VVVF inverter control.[13]
