The invention discloses a pantograph which comprises a pantograph head contacted with a power supply cable, a lower arm supporting the pantograph head to move up and down as well as an underframe used for supporting the lower arm, wherein the pantograph head comprises a positive pole collector plate and a negative pole collector plate which are arranged in an insulated manner and contacted with a positive wire and a negative wire of the power supply cable respectively. The positive pole collector plate and the negative pole collector plate are designed on the pantograph head, so that after the pantograph head rises under the drive of the lower arm, the positive pole collector plate is contacted with the positive wire of the power supply cable, the negative pole collector plate is contacted with the negative wire of the power supply cable, accordingly, a stable current loop is formed, and the charging demand of an energy storage type trolley bus is met. The invention further discloses the energy storage type trolley bus provided with the pantograph.
