ABSTRACT:
A head cap which comes into close contact with a nozzle surface of a function liquid droplet ejection head to thereby seal the function liquid droplet ejection head has a cap base; an absorbing material housing part which is formed in the cap base; a function liquid absorbing material which is filled inside the absorbing material housing part; an absorbing material urging member which urges the function liquid absorbing material; a sealing member; and a seal fixing member which fixes the sealing member to the cap base. The sealing member is fixed to the cap base in a state of urging the peripheral portion of the absorbing material urging member. There is thus obtained a head cap as well as a liquid droplet ejection apparatus in which the function liquid absorbing material can be easily replaced without impairing the original function of the sealing operation.
